Year 1 - Block 2: Fundamentals of Medicine I

Dr. Georgina turns difficult topics in genetics into clear and simple concepts that are easy to digest! For the first time I feel like am starting to understand the Central Dogma and related subjects better thanks to her. She's also greatly commited to student success by answering to students questions and concerns about the subject.

To the point. Good organized pathway explanations. Pedagogical presentation skills.

Easy to understand.I like how she uses examples to illustrate passive vs. active transport.

Amazing lecture, Dr. Georgina lessons are by far the best I've had in citology. Very clear and straight forward, perfect for the Mcat. Thank you!

The most important part of this lecture in my opinion is the analogies that Dr. Georgina offers. It really help us to understand for example when she associated the Golgi Complex with a Fedex facility, or when she connects the fact that liver cells have more SER since one of its important functions is detoxification.

I like how she breaks down the information in small and easy to understand pieces. There's no need to overcomplicate things like other science teachers love to do.

So clear and to the point - perfect - love this video

Very well explain and the quizes are a great help

The video by Lecturio provides an excellent overview of the electron transport chain and chemiosmosis, two of the most important metabolic processes in the cell. These processes work together to produce ATP, the cell's energy currency. One of the most interesting things about the electron transport chain is that it is a highly efficient way to convert energy from food into ATP. The chain uses the energy from NADH and FADH2, two electron carriers that are produced during glycolysis and the Krebs cycle, to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is like a dam holding back a reservoir of energy. The ATP synthase enzyme then uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate. This process is called chemiosmosis. The video does a great job of explaining the complex steps of the electron transport chain and chemiosmosis in a clear and concise way. It also provides helpful animations and diagrams that illustrate the process.

I've reviewed the Video, and while it provides a comprehensive overview, there are a few points that need clarification. "Fatty acid synthesis doesn't occur in the mitochondrion; it occurs in the cytoplasm, sequestered from fatty acid oxidation, simplifying the regulation of the two pathways." Clarification: Fatty acid synthesis indeed occurs in the cytoplasm, separate from fatty acid oxidation that takes place in mitochondria. This separation allows for streamlined regulation, ensuring the balance between synthesis and breakdown. "Fatty acid synthesis is chemically similar to the reverse of oxidation, involving joining, reduction, loss of water, and a final reduction, making it essentially the reverse of oxidation." Clarification: Fatty acid synthesis does indeed involve joining of acetyl and malonyl units, reduction steps, and removal of water, making it similar but not exactly the reverse of oxidation. The subtle differences in the chemical steps are crucial for the controlled synthesis of fatty acids. "The enzyme acetyl-CoA carboxylase is regulated through phosphorylation by AMP-activated protein kinase and allosteric binding of citrate, ensuring the balance between synthesis and cellular energy levels." Clarification: Acetyl-CoA carboxylase, a key enzyme in fatty acid synthesis, is indeed regulated through phosphorylation and allosteric binding of citrate. This regulation allows cells to respond to energy demands, modulating fatty acid production accordingly. "Fatty acid synthesis involves a series of steps catalyzed by the multifunctional enzyme fatty acid synthase, where individual activities within the enzyme complex work together, ensuring efficient fatty acid production." Clarification: Fatty acid synthase, a multi functional enzyme complex, plays a central role in fatty acid synthesis. Its individual activities work in harmony within the complex, allowing for the sequential addition of carbon units and the creation of fatty acids up to 16 carbons in length.

she is doing very well in explaining the topics and precise.

Great Lecturer..well explained. Every section of lectures are meticulously explained. Clearly understood.

Great material easy to learn good pictures …..thank you so much

Simply explained. Can't emphasize more how important this is

I like the immediate quiz and 'notes' format after each video.

The information is presented in a way that is easy to understand! Thank you ????

Helpful vik of birth and postpartum doula of birth of a few days to get the best of

The analogy of the central dogma is the best explanation I've ever heard!!

A great summary and introduction to an important but sometimes confusing topic. The questions following the mini lectures sometimes seemed out of sink, covered in a later lecture, etc. For students using this as a key resource, it is essential they understand that using the suggested textbooks and answering all the questions is necessary if preparing of licensing exams, etc.

Clear and understandable concept with actual molecules shown aswell which is very helpful.

I wish there were more foundational details included. I think Dr. Cornwall presented the material with the expectation that the listener already has a solid foundation in genetics.

I appreciate the approach to clear concepts and road map to the subject matter.

Unfortunately, Dr Cornwall confuses an already confusing topic. Waste of time that i don't have

This subject was amazing to learn, and Georgina makes it easy to understand, so I could say that really loved this course, thank you.

Well structured and comprehensible. Ms Georgina Cornwall makes pleasant pauses between sentences, speaks clearly and explains so that it is easy to follow. The questions afterwards are also very helpful.

I understand that medical genetics is a difficult course to review but improvements are definitely needed in the following areas: 1. State and simplify definitions. Too often i need to refer to Google for a more basic explanation. 2. Please stop assuming basic knowledge is still fresh. I haven't study genetics in 7 years and i have forgotten EVERYTHING! So, along the way and with each new concept please give some foundational information.

I am enjoying the lectures. I have two, very minor issues. 1. They are a bit too "granular". Some are so short as to prevent you from digesting the material as it is presented. 2. On several occasions, the questions were not covered in that segment but rather in the next!

Topic is not comparing the topics from previous topics in the table form. Then students will remembered

not explned wel as the topic is difficult and you made it a lot much boring

As a retired physician, still professing clinical subjects at a medical school, it is great to have an opportunity to revisit topics last studied in depth in the 1970s! It is presented in clear and digestible aliquots and in a logical sequence by qualified lecturers.

The teaching is basic and does not represent material tested on USMLE exams. The concepts are taught by an instructor unfamiliar with the actual exam. Technically, questions pop up in the middle of a sentence and sometimes before the subject matter tested was mentioned.

An excellent and detailed description of each phase with emphases on correct language.

Ms Cornwall presentations hard to understand with no clear imaging and orientation of the slides

Concise and easy to understand content. Thank you Dr.Georgina!

Great review for practicing physicians who have been out of med school for some time.

Literally worst professor ever, she seems so desoriented and feels like she haven't even prepared the class

It is too simple like introductory biology. We need more advanced molecular biology

lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.

I really liked and very helpful lectures thank u sir for your explanation

Great way to remember the three portions of the ribosome!

I, really, liked ALL of Dr. Cornwall's lectures, but did NOT find time to rate them! I am, still, trying to put it all together because molecular biology is my most difficult subject, but Dr. Cornwall put together much that I knew -- and I am far better off than beforehand! I, definitely, now understand as much as any medical student ought to about molecular biology -- and thus, I am glad that I made notes the whole way, giving me paperwork to re-think all that Dr. Cornwall taught me! Thus, I wish Dr. Cornwall the best and am grateful! :)

Breaks concepts down easily and love the review questions. Helps solidify learning.

Thank you, Dt. Cornwall, for this chapter!!! It was very useful and finally, with the help of your tips, mnemonic and your awesome teaching style, I could understand the process!

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.

very new insight to explain macronutrient and fruit for thought

Very dense lecture. Maybe a bit too in-depth in some places, but excellent discussion about the importance of carbohydrates and the key enzymes and reactions that underly the process.

Really liked Enough chemistry to explain it / not more Shows that she is passonate about the subject

Excellent summary and overview. Read the concept pages for more detailed info.

Georgia Cornwall has done a conscientious job at teaching molecular and cellular biology -- and I enjoy it daily! :)

Awesome lectures by Sir. he explain every step and every single reaction with detail thank u.

It was informative in a simple way and the question after make you make sure you got it

There are mistakes in the video and they make the material more confusing than it should be.

A very concise content with relevant short videos and quizzes. Great program

I can easily follow the sequence of information. The important details are also emphasized, making it easier for recall.

I really like the explanations and detailed structures used. The structures make it easier to understand.

Very clear and easy to understand. I enjoyed the visuals.

The explanation are cleared. However, they are not included many scientific terms and scientific details that necessary to well understand the content and to do well in the MCAT exam. In other words the content of that lecture are too simple for MCAT students.

I understood very well the topics. I learned things I didn't before in school

very precise, for a person with basic knowledge it is very helpful although I think it could be a bit difficult to understand for someone who does not know anything about these issues.

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.

The explanation about the carbs are very clear and detail. Which make easier for any student and professor to better understand the carbs, their pathway, and the enzymes that work in those pathways.

I love cell biology and this classes are amazing. Thank you

Thank you so much It was great I enjoyed watching these videos

How can the process of charging of tRNA be explained if the concept of tRNA has not been presented? What tRNA does and then how it's charged. I am loosing too much time googling stuff. Maybe it has been presented, but it's not part of this playlist, which should be complete.

This course is easy to understand and memorize. I am 100% recommending this course to anyone in need of learning sciences.

Very good teaching. Very good images and very good explanation.

This explanation was not clear at all. I had to research a lot of information elsewhere to understand the concepts presented. This is the exact opposite of what is to be expected of something that should make students life easier.

yummye yummy yumme yom? yommer yom yom yom; yom yom yom.

Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.

Concepts are very good and explanation is amazing. I'm in love with it

Amino acid MetabolismThe lectures are very thorough and give good details about what is high yield.

very good knowledge gained. Learnt a lot about RNA and DNA and messenger RNA

very clear , and natural. High yield, very in depth. Great knowledge gained

One of the best teachers in Lecturio my personal favourite class

FINALLY! I get replicated homologous chromosomes! Professor Cornwall cleared up a haze I had about this point for years in 3 seconds. I don't understand why there are not more people who emphasis the difference between homologous and replicated homologous chromosomes. Thank you Professor Cornwall.

The concepts mentioned in this lecture are very confusing and poorly explained. She made no effort to clarify the meaning of homeodomain, homeoprotein, and other such concepts. Also, she seems very unsure of what she is teaching and the speed is too fast to properly retain the information.

It was very comprehensive and I loved how easy it was to understand

I liked the course ,but a little more explination is needed in each of the clases

All of the videos on this topic are very good, thank you!! It made me finally understand it. I wish we would have more details on the pathologies related to the Purine and Pyrimidine pathways.

It was awesome factual and easy to understand.Amoino acid Metabolism clear relationship to general human Anatomy.

Amazing Dr. Kevin! Thank you very much for this course!

Short and simple. Right through to the significant things. Thanks to the professor.

I appreciate these refresher and very well-explained building lectures.

The content of the lecture/presentation is excellent. Has somebody else prepared the material?

It is Clearly clearly Clearly clearly Clearly clearly Clearly clearly

in depth knowledge on DNA splicing, ecor 1 and so the base pairs want to stick together and then ligase comes along to stick together the backbones, the phosphate-sugar backbones. Here you can see how the two pieces come together and now we have a recombinant DNA molecule. Again, we are generally looking at a circular chromosome and a foreign piece of DNA being inserted into that circular chromosome and so we'll see two ends of sticky ends and insertion of that sequence.

This lecture gave me a brief knowledge on how rDNA is made.

Easy to understand I like that subject Clear explanations relevant for my dream job

Wonderful, simple and easy-to-understand video. Finally got it

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.

I liked the lecture. It was clear and concise. I liked it better if the lecturer used more visuals of techniques.

Very informative and detailed. It allows you to understand the concepts on a fundamental level.

The best explanation, Concise and to the point. Thank you so much.

Love this lecture. Dr. Ahern explains much better than my professor.

I FULLY recommend!! Definitely has help out in my courses.

I liked this lecture and I also like this teacher. I just sometimes find the explanations a little be confusing.

A student could do this lecture and it would be easier to understand. we expect better lectures from professors.

best explanation of the iron transport on the web that I have come across. Good clear diagrams.

They give clear explanations on all topics in such a way that it is easier to grasp. I personally enjoy learning more about a particular topic and Lecturio is the perfect platform to do that as well. I highly recommend Lecturio to all students for better understanding of relevant topics.

I believe this course is an excellent review of genetic basics, techniques and clinical correlates

Very good lecture! Interesting clinical correlation (celiac disease). Thank you!

I'm really enjoying Dr. Cornwall lectures, I love the way she explains things!

Clearly presented talks and material. Very useful for undergraduate students.

Comprehensive, latest information presented in an easy to understand formats. Thanks!

I really appreciate how Professor Ahern broke down this topic (no pun intended). He does a really good job at tying things from other lectures together really bringing these pathways together while also trying to enrich our understanding of the context behind em. Thank you for your hard work!

I honestly had a lot of fun listening to Professor Ahern. You can tell he is really passionate about Biochem. I learned a lot. Great course if you're interested in understanding aspects of the metabolic pathways conceptually while appreciating the details/context that enrich your understanding of them and how they are interrelated.

I liked the way the R and T states where explained. It all became very clear

I like that Dr. Ahern's way of presenting the topics is informative and does not make me sleep. Usually, our classes make us feel drowsy because of too much information. It helped me understand the concepts more and I was less distracted.

It was easy to understand, and some details, which i think was enough! not too much information, but enough

Difficult to memorize all pathways I think it could be more interesting

Like the step-by-step discussion. Make it easier for me.

Covered a vast portion of the basics that are the most important part of the foundation. The structure of the course is phenomenal and the way it is carried out is engaging and made extremely interesting. Concepts are crystal clear after going through the whole course. Thank you so much, psyched to have found this! I only wish this material was downloadable for future reference. Hoping it could be. Thanks again! This has cleared the slightest doubts Ive ever had, hoping to have many more courses conducted by Georgina Cornwall.

not very engaging with the viewer, and it could be even more dynamic

This topic is OVERLY simplified. It needs more in-depth explaination, which she claimed to offer later. But this brief section creates even more confusion... Maybe it is better to do a PROPER introduction, or just cut this one out... Also, she herself seems to be unsure and confused. I am not sure what her profession is, but DNA doesn't seem to be a topic, which she should lecture on... In the middle of the video she just blanked, and kind of skipped on some points... (That's not the first time or first lecture that she does that...) P.S. The powerpoint is also not accurate... The coding strand around 0:52 is indicated as template strand... This lecture is quite disappointing, and frankly, a very low quality compare to other Lecturio's lectures.

Comprehensive course with exemplary format & teaching style to explain core concepts.

Aminoacid metabolism Is not easy to understand but still good !!

fast confusing order of explaining Its not like it simlifies anything the way its explained is quite fast and confusing very mono tone

More organization is needed to explain this lecture because is an important part of the DNA synthesis.

It's well presented and relatively easy to understand. It has helped me understand various concepts

I love her course. She explains in a very understandable way.

Professor gives a very clear explanation, easily understand. Thank you.

Content is spot on. And quizzes at the end of each videos are very helpful. Hope Georgina used a cursor or infra red light to point exactly what she was talking similar to other lecturers from other videos. An animated video clip of how each or some of the topics would be very useful.

Hello, I love supporting women in science and education, etc. I also will share my honest opinion to improve the educational site. This lecturer, while alright, is not the best you could get for Lecturio students. Her constant glancing over her notes is distracting and she is not very well articulated. Even though she is Ph.D., she has not digested her lecturing materials to the master's level. It is very unfortunate that she lectures on one of the most important subjects within your platform. Why you chose her? For the sake of diversity and involvement? I am sure there are much better and knowledgeable lady lecturers. Did not you see the disengagement and flaw after a couple of her lectures? Was she so cheap?

I am no longer scared of metabolic pathways. thank you so much.

I liked to much because maintain the point of what are she explaining the theme with clarity and didactic form about the macromolecules of life the first principle to begin the content of the nature of the Body , systems organs ,tissues and cells.

Incredible Easy to follow the class The professor had my attention all the class

It was hard to understand It could be better another way to explain the topic

Biochemistry by Georgina Cornwall is not good at all, she reads all the time and she doesn't even know what to talk about.

She didn't talk about the template strand. the prof fumbled with the coding strand and im actually confused if the coding strand, or the tremplate strand matches the sequence of the mRNA. She definitely seems disorganized. It didn't flow at all.

I liked these explanations, but if you are a college student this may not be for you

Very condensed, but a well-taught lecture. I love the teacher´s style.

Nice explanation, very useful, easy to follow. very useful reminder of basics.

SHE IS NOT CONFIDENT IN TEACHING AND RUINS THE MOOD OF LEARNING

Its excellent because there is more physical and clinical correlation and enzyme mechanism simplified

I noticed that there weren't any lectures on mineral metabolism in the library. I think students would really appreciate it if you made a module on this topic as it has a lot of biomedical importance and some relevant diseases are associated with it.

i like but the fomr like the professor express can distract a little

La verdad es que es muy buen curso, el ponente explica demasiado bien y me gusto mucho qué hay actualizaciones

Each and every concept is explained with each lecture it has helped me in getting to know things well rather than just learning.

I use Emery’s Elements of Medical Genetics 15th edition as primary study material, which i recommend for anyone to use. I decided to take this course as a supplement and ended up confused and annoyed. Simple learning objectives of this course lectures are harder to understand due to poor explanation and as far as i can tell the professor seems stressed, disoriented and confused herself. Lectures need a rework. Despite that, the articles are pretty good and helpful, PowerPoint slides are useful to an extend.

The introduction provided me with the basic concepts of genetics

I could not understand it good at that in my university college friends

Great explanation about the Bohr effect, thank you very much doctor

Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.

one of the best teacher ..yo mam ............really enjoyed it

i liked the details and visualization. should have been there more mobility in the slides tho.

Need to explain better as it is very complicated and confuses us even more than we were before

Nice course very complete in every sense, I like it, keep like that.

Awesome overview! Thank you! Particularly liked the gluten example. Also graphics were good - will stick in my brain longer.

Lesson was so fast and not understandable .Lecturer should have gone from easy points to harder points.She could not make it easier this topic for me .She did not use her hand at all during the lesson.This is so lazy way for giving a lesson and unproffesional.

The objective was to mention which diseases are AR and it was covered correctly

I dont know if its the diagram or what the doctor is saying but i just cant understand the MAP kinase and the GEF and everything else afterwards

Prof Ahern explains very well & makes the key steps/enzymes memorable (eg PEP is full of pep!)

So good explications with a nice and simple way . I really appreciate your effort .

Explica las cosas super simples y puntuales, se memoriza rapido de esa manera

she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

Very clear and succinct. May have gone a bit too fast, but that's always manageable

I recommend include the cc out of slides screen, the letters do not allow to watch the information

The lectures are very thorough and give good details about what is high yield.

adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o

Basic topics which i had difficulties in understanding has been well explained and now I have fixed the knowledge :) Suggestion: it's hard to cover the extremely fast growing biotechnology topic but I guess "omics" would be good to add

I really liked it and enjoyed Dr Cornwall'ss explanation. The only issue was that the video slowed at some point.

Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.

Most of it was good and understandable but towards the end, it became quite confusing to follow along.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.

lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.

this is amazing thank you , i gained a lot of info about viruses that i have not know before

I am in my first semester of Bachelor of Science in Biomedicine in Switzerland and the courses are helping me a lot. I can watch your videos after a whole day of studying and I am always having fun! I get a great overview and know what the most important concepts are. I also have no issues remembering what I learn here. Thanks a lot! I learn new things while answering the quiz questions as well, they are smartly structured and help a lot as well.

very clear explanations and the questions helped me understand the content

Love your lectures, Professor. It is helping me a lot reviewing Biology as It's been years since my basic science years.

this is a good lecture i really understand a lot of thing i haven't know before tysm

Although the whole course (and actually the whole of Lecturio) is absolutely wonderful, I enjoyed this lecture with Dr. Cornwall so thoroughly, that it felt like time was passing by rapidly! Before I knew it, the lecture was over and I had learned so much! Dr. Cornwall has a way of explaining things that makes you understand is the matter longterm and makes you curious to look deeper into it. Thank you very much for everything! Eileen Dara Greetings from Belgium

simply explained so well understood, very well done. lots of info but concise

I select leturio because its teaching method is very awesome knowledge base Usmle type based

i understand it though, you just need to concentrate on what the prof is saying and correlate well with the diagram then youll understand

It's good, informative not as detailed as I need it to be but it's a good framework to build on

Great concise videos covering salient points in biotech. Most of material is well presented though some concepts I've had to supplement with other sources to fully understand. Overall, great useful series. Thank-you Dr. Cornwall!

It is a good introduction for the following classes. It's not confusing, but more information could be added

Clear and concise. well-explained, clear diagrams, builds on my existing knowledge

Liked it too much as it's so easy to understand ????...but cannot afford premium ????

First of all, I like the depth of this lecture and Professor Ahern is clearly very knowledgeable and concise on the the topic being discussed. And I also like due to the fact that this video is clearly a high-yield resource which is very helpful for my upcoming medical exam. However, I believe that this could have been better had the previous cycles preceding the formation of OMP explained as well in order for us the students to be able to get the essence of the information better. That's all I have got to say

Dr. Cornwall is awesome! Her lecture are clear and concise. She makes the material so much more digestible.

Dr. Cornwall is fantastic! The biotechnology series helped me SO MUCH going into lecture.

She keeps it short and simple. Great work in this video. It's great prep before going into a lecture!

Excellent Lecture from lecturio; I highly recommended for students from medical school. It is an excellent learning platform.

I love lecturio, it's the best app in the world. Lecturio has everything you want and can help you to be the best in your class and also be the doctor you want. Lecturio is an opportunity that can give you the change of your student life.

Very good review .enjoyed the enthusiasm. Visuals were ok but not really understood.!

This lecture is amazing and I loved the explanation regarding the conformational change of hexocinase during the reaction.

His explanations are very good. Biochemistry made easy!! He is very good in teaching.

beautifuly explained. thankyou!! Every point in every step was explained nicely.

Interesting and informative! Expounded well on complex concepts and gave a riveting lecture.

TOO SIMPLIFIED AND IT SEEMS LIKE THE LECTURER WASN'T WELL-PREPARED FOR THE LECTURE KEEP SAYING NONSENSICAL WORDS. I AM REALLY FURIOUS AND FRUSTRATED LISTENING TO HER LECTURE.

Me agrada como explica las cosas la Dra, creo que lo hace que sea entendible de forma sencilla para cualquiera

La Dra explica muy bien y de manera sencilla, algo que me gustó mucho son las analogías que utiliza para dejar claras las cosas, creo que eso lo facilita

I belive she is very clear and resume complicated topics nicely.

I suppose it depends on your learning style. That is, most of the medical students I've spoken to, appreciate concise and coherent lectures - Unfortunately, in my personal opinion, this micro-lecture lacked the fundamental high concentration of information that most of us are looking for - to take notes, and practice the spaced repetition model. Instead, her speaking pace, and vocal expression are slightly too fast and the way in which she attempts to outline a basic idea isn't linear in nature which leads the viewer wanting to know more, while simultaneously trying to ignore the off-topic rants. Note: Clearly, she's qualified to teach - however, valid of a point that may be, doesn't mean she has the practical communication skills to do so. Therefore, this is not a question of intelligence, rather - communication and linguistic expression. There will certainly people who prefer this method, I however, can not recommend.

I had many doubts but with the lection, I improved much better

The lectures seem to cover all the necessary contents, but it’s often difficult to understand the topic until I go over the video again for several times.

This lecture clearly points out the differences between prokaryotic and eukaryotic cells in protein synthesis. It would be helpful for those who wish to briefly know how proteins are formed in each type of cell.

It is a good explanation for a complex topic, with only the most important

Teacher speak slowly to help me understand Glucose in my body

me gusto muchísimo lo recomiendo a todo el mundo que quiera saber mas

complicated topic but I think I got it, though the Tyrosine kinase itself is a bit complex

I like the format - the lectures are "short and sweet". The lecturer is reasonable easy to listen to. Perhaps it is just because this is a foundation course, but it does feel this material may not be in-depth enough for USMLE step 1. (Or perhaps because it's re-used for non-USMLE students?). The questions are just "okay". There are a few errors, and a couple questions could be worded better. It also seems that some of these questions are testing material that seems only marginally important, and may not be very "high-yield". I wish there was an option to flag review questions to not be included in the "spaced repetition". The "spaced repetition" idea should be for memorizing the most important details, and I don't really want to be memorizing questions that I think are of little importance, incorrect, or poorly worded. (It'd also be a good way your you at Lecturio to decide which questions should be revised - if many people flag it as "don't review again", the question probably needs revision.)

not clear voice . . . . . . . . . . comparatively worse than other videos, others are good.

Amazing way of teaching, compact and efficient. Really good job, keep doing it Mr. Ahern.

Has high yield infos which are not in other lecturer's lectures

As I stated in prior lessons, Dr. Cornwall is such of an amazing instructor!!! She makes easy to understand heavy contents

I would like to inform you that from 3:54 onwards there is neither the transcription nor the translation in other languages. I hope you will solve it as soon as possible because some concepts I cannot translate from English into Italian. Thank you in advance

the instructor is very clear and is easy to follow

Dr. Cornwall did a very great job with this.. The big picture simplified everything and made studying into little details easy.

very didactic I really enjoy Dr. Cornwall lectures, definitely Lecturio was the best addition to my preparation

el contenido esta muy bueno, solo que la traducción tiene falencias y dificulta entender los conceptos adecuadamente.

Everything is confusing. The diagrams and what she was saying didnt allign. ALso she never gave the answer to the number of chromosomes in each stage of meiosis and mitosis

My professors at university failed to explain lipid metabolism in an understandable manner. Prof Ahern does a great job in explaining complex topics and I am really grateful for that. Thank you

Well explained and easy to understand the concept. I'm on the right track and enjoying the course.

the explanation is complicated it could be simplified more better

Very well taught, good refresher. The high yield points are in there too.

Very well explained. Would have appreciated had the lecture been a bit more comprehensive on certain topics, like in DNA replication and also a dynamic step by step diagram of the process would have been better to understand.

The lectures are great... But I just feel like they are too expansive... Not very suitable for a dedicated study period

Excellent breakdown of key topics and very easy to follow.

Kevin sir explanation is very very nice and it's an extraordinary talent and explanation but little more information should be presented in power point slides so that we can learn more and more by step by step .. Thank you sir From Sanjeev India

the explanations provided for each disorder weren't very thorough nor well explained

It is very concise but it provides enough information. I am very satisfied with Lecturio because this course and Biochemistry are exactly what i was looking for.

The video episodes are way too short, need to go back and start over every 3-4 minutes. I think there should be a option to view the topic in one full video. Otherwise the subjects are well covered in an understandable manner. Many thanks

The way of teaching of Georgina is really impresive, i understanded everything. The best classes ever.

Very comprehensive lecture . It' s clear and simple. Thank you for your work .

this presentation was good and the way sir explained the concepts was nice

Great Great great great great great great great great great

O really like it , because the lectures are very clear. And I understand everyrhing.

difficult subjects are explained by simple words by Georgina. Thanks so much!

Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.

I recommend everyone to Follow the 100 Day Study Plan given in Lecturio App. Its Amazing.

hi first of all she is talking very will as good speaker and the explanation in different lecture was so systematic and will prepared and hit the main points that I'm really interested to her course of biology.

Great lecture! Very simplified and friendly explained. Thanks so much !

Each RNA should be shown in the picture like above

It is a good course but the content here is not really high yield.Do we need to spend so much time on it?

Very clear and useful for me to finally get a grip on this topic.

i can't understand why a lot of amazing videos have 1star points

I find the teaching style to be effective and well planned. I use lecturio for supplimenting the topics taught in my classes

Dr. Cornwall makes the topics easy to understand and retain. Her approach is not overwhelming but yet not so simple you are bored.

The lecturer tripping up make it a little difficult to follow but it is made clear in the end.

Talking about things that aren't on the slide https://www.ratemyprofessors.com/ShowRatings.jsp?tid=833581

Good course but we need more practice on the problems

Very detailed. Moves through information and a good pace. Sifts out the important information versus stuff we don't need to know for the exam.

the concepts are clear and the time is enough, examples are short.

Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!

This is incredibly difficult to follow with the lecturer mis-speaking constantly

I believe the term is entropy is misused in this lecture.

Excellent lecture, well explained so I could understand it. So important to understand and not just memorize these topics.

Excellent lecture. Understood Bohr effect better than ever. I love these lectures.

Most of us studying at this point (USMLE Prep) know this stuff well, however; this does provide a good refresher to get the juices flowing in the right direction while studying for the boards.

Misuse of the words fludity and stability as if they were synonyms makes answering the question at the end confusing. Other than that, it's a good lecture.

This videos are amazing, the professor is excellent and his explications are clear

He is a very Good Teacher as he teaches as if he was narrating a story.

Thanks Mr Kevin for your time, dedication and preparation, blessings my man!!! happy 2020

Awesome analogy great lecture! Very nice lectures overall I really enjoyed them. even though I have taught this topics and I know them fairly well. I enjoy little gems of information I received through these lectures, and new understanding

need another resource for this topic as these lectures have confused me more

if the professor says she gets it confused when lecturing she should not be teaching it.

Amazing explanation made me understand the concept clearly in a short time

This is one of the few videos in this video series where the video cuts before the lecturer is done talking or before she's done with the material for the section. For example, in this one she only discusses E site and video cuts... what about the other 2 sites on the ribosome?

The instructor reading off the podium is not appreciated. It doesn't entice the viewer to keep watching.

I like a lot both the explanations and illustrations to the topic.

I like how Dr. Cornwall recaps chemistry and relation to energy to cells. Her hand motions help with my learning and understanding. Thank you.

Great professor. Has almost everything needed for my course in Biochemistry.

Didn't explain clearly and concisely which each type of RNA was as well as providing its clear function. Additionally, it is best to provide the correct definition thus, followed by an analogy. Starting with an analogy of how the different RNA types can make the lesson hard to follow as well as, causing confusion in the actual definition of the term. This particular video was hard to gather information from.

4/5 also add on the replication bubble but as far as the other information well done i understood the concept

I like the practical comparisons used for better understanding and remembering the topic, makes it much easier and more entertaining!

Concise and to the point for basic understandment of the subject.

The lecturer is very thorough and makes the series interesting

Thank you dear Ms Cornwall l easily grabbed basic elements and mechanism of cell biology with your videos Best wishes

Muy buen docente, se nota que le apasiona su profesion y la ejerce con entusiasmo.

It was a great lesson thanks for everyting short and briefly everyting.

A huge thank you to Prof Ahern! You explanations are very easy to understand and your lectures are a huge help to get a better understanding of biochemistry topics. Thank you very much!

I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.

Really good discussion. I would love Dr. Ahern to by my mentor

I really liked the videos they very clear and easy to understand , they best part is they are short and precise to the point .

The marcomolecules lectures are very good with excellent explainations of content

The DNA Repair lecture was not very clear at all.

Great lectures, very clear and understandable! Thank you, Dr Georgiana Cornwall!

Great lecture, Dr Georgina explains clearly what we are required to know

Helped me understand better some concepts as she explained clearly

It is a great parsimonious source for understanding the mechanism in which amino acids build into protein and how amino acids are broken down through metabolism into various molecules inside the body. The lecture also provides the structural frame understand the basics of amino acid regulation through metabolism.

The explanation is cristal clear with examples and illustrations. Good picture of ARN structure.

Great lecture which allowed me to understand the topic much better than I was taught

Explains concept very well with good analogies that further enhances my understanding.

The knowledge is systematic, but I wait for long time to get a answer to my questions. And I still get no feedback.

Dr Cornwall has the gift for teaching!! She explains things very well, thank you!

Not too many details. Right to the point and easy to understand!

The module is complete but the questions can get too easy

I really enjoyed the video and it made me learn, also I liked that are short videos

They are so awesomely explained and very helpful thank you. I’d love the videos to have that ten second rewind or fast forward arrows like YouTube does, and then it would be perfect.

she was understandable! i liked her! i am so prepared for the next test we will be doing

Very concise. Great illustrations. Thank you. Thank you. Thank you

The professor did not do a good job explaining concepts clearly, went too fast, covered little material

there wasn't enough details at some points. The topics, for me, are a little tough and the techer wasn't seems to be confident with the material. although the slides are very helpful to understand the topic.

Concise, easy to follow, great drawings, post questions provide a good summary of key points before

I couldn't follow this lecture - it was not presented well at all.

amazing lecture, finally i understood the tertiary structure for the first time

Good and informative, no bad comments. Good lectures and lecturer

Good, where are the rest of the organelles (like peroxisome)

Need lot of detailed explanations.. especially in videos. The teacher is really good but the script is lacking too much.

Excellent ! I finally understand the topic after forgetting it many times ! Much better than First Aid !

Simply explained with a little history that made it fun and also helps keep the connection to the content, So much of medical knowledge is facts and figures which can easily become blurred in my mind. The connection to history helps this content stand out in my head! Thank you!

It helps me a lot with my presentation, I was having a hard time understanding this topic and after see this lecture it becomes easy to explain. Thank you so much.

I really like the lessons and I think they are really useful

Wonderful examples of the Hardy Weinberg principle. The exercise is explained step by step and is understandable in the first explanation.

I love this app but can get a little confusing when the professor uses the wrong words or accidentally says the wrong thing. Do you not edit errors out? It’s a great platform just needs a few tweaks here and there.

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

Easy to understand and fun! Really useful! Great examples are provided!

Gives you the basis and covers the necessary topics for a good understanding .

This is pretty good introduction! haha how to control the cell cycle

I thought that this was very thorough and went over lots of the material that my current professor is going over. Some of the questions were either a little simple but reiterated take home points, or were left-field as the material was not covered in the specific video I just watched. Overall I would recommend this course to anyone struggling in genetics + read the comments because she does a great job in answering and clarifying questions you may not know that you had.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

This particular class video is not very helpful at all. I feel like genomic imprinting can be explained more efficiently and more clearly than what is portrayed in the video.

Actually I saw the YouTube add . And I watched the lecture . The information is given in short and precise manner. Understood everything.

I loved the correlation with margarine and butter, it helps to understand and remember the topic.

it is really amazing lecture & has been organized well thank you

I loved how I understood the bigger picture in the end of the lecture

Clear and Comprehensive explanation. Not too detailed but enough to understand.

I like so much the content of this course and how the doctor provide the information

I found this lecture very concise and easy to despite being quite basic. I have always struggled with understanding atomic structure and feel that it's due to information overload. This lecture provides just the right amount of information to build on.

i knew next to nothing about molecular genetics, however after 6 weeks using lecturio ive gone from 20% in the practice tests at university to 70-80% each topic is subcategorised, easy to follow, and Dr. cornwall not only illustrates brilliantly but also delivers the otherwise difficult to understand material in a clear and concise manner,

Concise with good use of slides and professional presence and dress.

P53 GeneRate this lecture P53 Gene Rate this lecture P53 Gene P53 Gene P53 GeneRate this lecture

Very in-depth discussion of X-linked inheritance. A very good resource for studying for exams on human genetics.

I liked it very much because it helped me access materiel that I already new without further complications. It was very easy to comprehend and I will recommend this to everybody needing this for whatever the reasons you need it for.

Appreciate too much, because after many readings in the books, finally I understand clear having the big picture of this topics . Congratulations to the Teacher .

Very much explaining After I did this topics know is easy to undeerstanding

she looked like she was reading from a script and not focused or natural.

Amazing lectures. Simplifies complex pathways and process. Really fantastic! Watched every lessons.

she explains it to the point and doesnt waste time going around the topic.

This lecture was explained super clear and to the point. Thank you!

Well done! Very targeted information. For those that say it’s not as deep as their classroom lecture, it is not designed to be. Again,what we are supposed to get out of this course is the high yield information...and we are getting it. Thank you so much Dr. Cornwall.

Very eloquent :) my favorite on this website! would definitely recommend.

thanks for your helpful for the all lovers of education

A good introduction. Very schematic and overall easy to learn basics.

Easy to understand...high yield information....great graphics,well done!

Easier to comprehend with the use of great illustrations. concise and crisp presentations

Made it very easy to understand. Thank you very much!

Almost no information really disappointing. Use Step 1 2018 page 46 ... Even a student could have presented the topic in more depth as it is important.

a tough subject, but Dr. Georgina made it very easy and palatable, thanks soo much.

I just want to admit that this tuition is a hard one and she made it very easy.

just excellent , the content and the preparations were realyy excellent and goes very easy.

I believe that she is a great lecturer but, the issue is the way of delivering the lesson and how much was she ready to record the tuition. anyway it was a good experience for both of us, she let me search a lot for the genetics to unwind condense informations :)

Very disorganised way of explaining concepts It would be much better if things were presented in more detail and if the presentations were structured adequately

Concise and clear beginning in cell biology and homeostasis to warm up.

The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.

amazing ! thank you so much dear dr.Ahern , i was always scared of biochemistry ,but its the first time i finally get to understand it and i owe it all to you. My committee exam will be in two weeks and im hoping to finish this course plus few more lectures from fat metabolism course. also special thanks to lecturio for preparing such a great learning system opportunity for us.

I wish all professors prepared students for Biology courses with this explanation. Thank you for addressing this concept!

Nice succinct intro with basic overview -- key points are highlighted

I feel like she is just reading notes that she has been just handed over.

The presentation is simple, short and concise preparing students for more detailed content. I believe that this is an efficient approach toward a broader base of an audience. Thank you!

For the first time ever, I got AA right. Thank you!

I'll just say thank you very very very very much!!!

You do a wonderful job of clearly and concisely breaking down concepts.

the course was good, the first video was condensed with a ton of information and I think you should maybe think about splitting this kind of videos in the future, I was finding myself watching other youtube videos to study this subject. it is always good to use plenty of different source of information to develop a wide perspective on a subject. but in this case, I want to rely on lecturio only.

Dr. Cornwall is very thorough and paces herself very well in relating core concepts.

Love him so far, clear concise and to the point and also very enlightening

most of the things i catch from animation while only little from lecture (for which i had to pause the video to read all those stuff written there, which is time consuming). mam's speech seems quite a kind of nervous, suffocating type

Yea, these lessons site wide need more quiz questions. Only thing holding this site back from being outstanding.

Genetics generally is a very confusing part, I think she made it quite interesting and I grabbed a whole lot

The explanation of concepts were precise and focused. I like the pictoral representations I'll recommend the lecture to my friends, who are taking USMLE Step 1

5 rating is what you deserve , i really liked the way you illustrate those key aspects

So much more simple than my lectures. Thanks for the detailed lecture. You're a life saver.

I needed an update on genetic like this one, i like the way is shown every part and all the details within, i recomend this article to everybody.

"... and we know that the DNA was taken up because the plant grows tumors OR NOT..." Taking the term "tentative scientific language" to another level!! LMFAO >D

In my school we will take this lecture in 2 hours!!! Way too short and superficial

lectures are very exciting and informative provided someone have basic knowledge of genetics. With reference to USMLE, I am afraid to say that is it is helping.

She talks too fast. Additionally, she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

As much as your stories are interesting for the ETC gradient It does not fit my learning style. It would be nice to have clear scientific language about what's happening. I can't write a story on my exam paper. Perhaps this is just me.

Highly recommended lecturer for Biochemistry! I like his method, he is attractive teacher.

Easy to understand and very complete. Thank you for your time, helped me a lot

Feels like she is not comfortable with information she is teaching. Accuracy of information (and spelling!) is sometimes questionable.

Great Explanation !! I wish we would have had you as a teacher. :)

Wow! Muchas gracias por todo el contenido muy bien explicado! Realmente fue muy interesante y, de gran aprendizaje asistir a todos los videos del curso "Introduction to Cell Biology".

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were

Its hard to pay attention on her lectures because she always pauses to read her notes.

great lecture, very simple and clear. I've finally understood bonds!)) thank you!

Brief, understandable, high yield information explained with illustrative slides by Dr. Ahern

I am a biochemistry student studying in the UK I found this so useful especially as a foundation in my initial year of study.

I love the visuals, her method of speaking and the transcript at the end

The combo of visual and review aided in maintaining info

This lecture and the one before were very confusing. You need to explain that the third energy level can technically hold UP TO 18 electrons (s,p,d sublevels) but it also fills up with the first 8 it receives. valence shells (energy shells) and energy LEVELS need to be better distinguished and not used interchangeably. Luckily, I knew the material and was able to straighten things out for myself using Google. How can I know that Lecturio will not have faulty lectures in the biochem module (material I'm not familiar with)? I am still within 10 days and am considering cancelling my lecturio subscription over this lost credibility in my mind.

It is very clear to understand. Great job Dr. Cornwall.

Prof Cornwall does a great job at presenting the material, catching my attention easily into the depth of the material while being precise with the content. Very easy to learn from :)

You make it much more easier. However, I still understand all important points. Thank you!

This guy deserves a medal. I wish I had a lecturer like this when I was in undergrad (or even now in medical school).

This entire series is the most eloquent and beautiful explanation of a terrible terrible subject like biochemistry I have ever seen to attended

She talks so clear, understandable.. just a little fast but i havent got bored.. Thank you..

I love it so much!!! It’s been a truly rewarding experience for me!

Good lecture, but not USMLE focused. This is more of a general biology lecture than a USMLE prep lecture. It seems to me that Lecturio is not making the difference between MCAT prep and USMLE prep. The lectures look more like MCAT prep lectures and not USMLE.

I like the way she expresses, you can easily understand her

Very good use of examples connecting to every day life.

best prof in the world explains everything so good that even a kid will understand

VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT

Really great explanations of the whole process. Was not happy that I had to relearn Krebs and ETC but actually found these videos enjoyable and valuable.

The lecture are awesome. It is just easy to understand Thank you very much!

Great enzyme analogy! Enzyme is the friend who puts his two other friends in contact with each other so that they can start talking and dating ;)

Nothing on how p53 relates to RB or how p53 induces p21 to inhibit CDK thus acting as a tumor suppressor by not allowing cell cycle progression. This info is found in the the First Aid for the USMLE so it is probably important.

I like the smooth flow of the subjects in this course and how they focus on small details that make you digest and understand the living human from very small details.

In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!

Not bad, but need to identify the polymerases better, as in the replication of DNA and RNA...

Had so much difficulty learning the enzymes on the pathways. This way was easy to understand it!!

There is possibly a mistake in galactosa geometric formula in the lecture

I’m following this course as I’m attending this course at my university, it very helpful, but I wish it was as detailed as our class are.

This is not a USMLE 1 focused topic, an important material for the step, it's so superficial either the question that is a first order question. Need to going deep in the topics, we're not an undergraduate students.

She broke it down to the very basic and helped me get a good foundation

The explanation is very clear, I'm early to continue watching more videos.

Understood the lecture clearly. Very impressed by how clearly he explains things.

Wonderful! An awesome lecturer, he just has a unique way of passing the message. Great work Sir

He explains it very well and at a good speed. He doesn't use to many difficult words so if your first language isn't english it's still possible to understand. Also whenever you have a question he answers quickly en thouroughly.

Me encanta como se enseña! Ya quisiera tener una profesora como ella en la Universidad!

I had to try so hard to follow what lecture was teaching, subject matter is quite abstract. All the same thanks for trying.

I had to try so hard to follow what lecture was teaching, i remember i enjoyed this better in med sch. All the same thanks for trying.

this topic is quite too cumbersome and lecturer didn't seem to be in control of material presentation

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Nice intro to genetics, subject that's usually scary but very well carried out. thank you

great lecturer with an incredible pitch and clarity but this subject rather fees boring and i tend to get the post lecture quizzes wrong but its all good. I need to read elsewhere but all the same keep up the good work.

i don't know but sometimes its very difficult for me to follow lecturer and i get confused with interchangeable terminologies but great job overall.

First of all I would like to say that I really appreciate all of the effort by the professors and Lecturio to do great lectures, however, I would like to say, as well, that you need to focus on the exam format (In this case - USMLE Step 1). For example, in this lecture it was asked: "Which of the following is NOT a lysosome related disorder?" that is pretty good, because it has a clinical context with the subject, however this " lysosome related disorder" have never been taught by Professor Cornwall.

The explanations and images are well coordinated, making the review more interesting

The explanations and examples were clear and right to the point

informative. good review for this basic area as it has clinical correlations

Very clear what is going on. I understand it much better.

very good outline and examples given in a step by step manner. Getting to like biochemisrty after years of putting this subject aside. Thank you.

Loved the lectures, especially the lecture on the electron transport chain. Dr. Cornwall had a really useful analogy of the ETC and kids (electrons and hydrogens) going to the prom (ETC) that really made the concept stick. Very good job!

It is very concise and practical it helps me a lot to understand in an easy way the collagen process.

The chapter about cellular structure has given me clear explanation and enhance my knowledge about the different functions that the plasma membrane assure. The course just makes my understanding of cell dynamic very straightforward.

I feel that the delivery is good but the content is not detailed enough, e.g. when talking about splicing, I think it would have helped to talk about what ‘snurps’ are involved and how this relates to initiation.

It's an excellente teacher! She uses easy analogies that you can memorize quickly and gives you a summary of your class (in my case). Greetings from México!

Excellent structure and content. Essential basics for chem and biol.Thank you.

Well organized backed with excellent methods of teaching & illustration. In summary, I found what I want in short period of time.

Thank you very much! Those extraordinarily awesome questions help me better understand the whole thing with details!

Wow, these two amines are very tricky, thank you very much, Prof. Ahern!

Me gusto mucho porque pude repasar el tema sobre la homeostasis.

very good, is complicated, but i understand everything, she is a good teacher

I cannot believe I am just now finding this resource during my dedicated Step 1 period. However, I am so glad that I found it now, right at the beginning of Step prep, rather than later. I plan to use this as one of my main resources for the remainder of time up until my exam. I realized while reading First Aid that, although I had known the subjects very well at one point, that my foundation was not as solid as it once was. This is perfect for reviewing and providing the big picture for everything. It's also an amazing resource for providing the "why" and "how" behind all the small factoids written in First Aid which is just what I need. It's so much easier to retain the information when you actually understand what is going on rather than memorizing a 650+ page book of bullet point lists/facts. This is great. I was a huge fan of Boards and Beyond, but I have since ditched that resource and am fully focusing on this one since this seems a lot more comprehensive and better taught (though Dr. Ryan has also done an amazing job too). Thank you guys so much for coming out with such a well thought out and developed and thorough resource. This is going to make board prep so much smoother. If I end up scoring highly on Step 1, I will make sure to write a review on Reddit, SDN, etc raving about Lecturio.

I wish all the other professors had her didactics. Pointing clearly the goals of the presentation before and after the lecture helps us to mentally organize the subject.

I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.

This guy is on top of his game at a ridiculous speed... I can't complain only if all others know their stuff like him there will be less confusion

it is really good ,some hesitation at the beginning but the diagram is very informative ,whopple hypothesis needs more explanation.

The course is informative and up-to-date, which is really important for me. I took my science courses before 2010; now, I’m preparing to take the MCAT. It is an excellent review of content.

Gooood job LoL and really a good story-maker????Thank you very much! Amazing, very impressive!

Thank you very much!! So funny and interesting! I laughed many times LoL also learned A Loooot!!!

I do not think there can be any simpler explanation of these concepts. Dr. Cornwall takes her time to explain these concepts in a way that they stick with you, and the analogies she uses engrave them into the medulla so that you can relate to the concept. You can't beat this! This is exceptional!!!! Thank you so much!!

First step to refresh and understand different concepts. Highly recommended.

This guy just knows his stuff, on point even with the speed of his speech he has mastered his slides. I almost got scared with the previous lecture in genetics but he managed to bring me back home. Very knowledgeable keep up the good work and add more clinical correlations.

excellent she is a very good teacher, the grafhics are didactical she explains in a very simple way, i like it

Care for details and passion/curiosity for knowledge are seen in this lecture. I gained a lot from it.

I LIKE THE PRESENTATION AND I LEARN . PROFF. USE A SIMPLE AND UNDERSTANDABLE LANGUAGE

I like the fact that the lectures are detailed and Dr.Cornwall makes it fun and easy to understand.

Very profesional, why is it said that bacterial chromosome has a single origin of replication and eukaryotic multiple origins

The course was well explained. It is confusing subject matter, but she did her best to make it understandable. She is funny, energetic and lively

This is course is still challenging me but i can understand how abstract the concepts are i think i need an in-depth review of course

Thank you Dr. Cornwall, I really think genetics is quite a difficult concept so you are doing your very best, i must admit its very confusing at times i will need go over the concepts again.

I really loved it, because PhD Cornwall made it really easy to understand.

This lecture was excellent in every way, I must say DR. Cornwall is a Pro in intermediate metabolism. I couldn't understand this processes better in medical school than she has made me.

Brilliant. I recommend this course strongly if you want to understand this topic.

Based on explaination. I felt there was some lack of informations. In some area needs to be more profound.

Its really interesting subject made easy by an interesting professor. I'm not sure if that level of details are needed for the USMLE exam as I'm using the USMLE curriculum, if its not needed thats fine it will be for my future knowledge hopefully if i get to keep in my head.

Great lecturer who is knowledgeable about the subject. However the animations in both mitosis and meiosis would have been in motion so the explanations were tuff to follow. overall good attempt. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

It was simply amazing. The knowledge I got exposed to was simply clear cut and delivered by an expert in layman's literature. I am keen to absorb more of Mr. Kevin Ahern's lectures.

This instructor makes this course enjoyable, and very easy to understand the materials presented here. I have already informed all my friends who are interested about going to medical schools about lecturio. Lecturio is a blessing to mankind.

Excellent lectures, you can understand in a few minutes the basics of difficults topics

Well explained she took her time tho but she did it well

Batalle mucho para entnder mis clases pero con estén curso tengo un mejor dominio de el metabolismo y me permitió realizar una presentacion del tema ????

An excellent, brief and up to date piece of information, ideal for quick recall

Good content, I like this course, but this particular class could be a bit clearer

Thank you so much Sir for brief description of all topics.

Well done by the professor with full of transfer sense.

couldnt understand a thing. Please try to use animation to explain better

Classes have an excellent quality, however there are small mistakes when you´re reffering to some specific molecules such as cAMP and cGMP because in some ocasions, you tend to exchange one with the other in just a few ocassions. Nonetheless, the overall course is excellent, with clear explanations.

The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!

I am having my genetics exam soon and this course was extremely helpful to better understand the information. Thank you !

Recommend this course to any medical students doing pre/clinical Helps with pathways and understanding breakdown.

u r so good like honestly amazing thank you so much professor

Excellent! Well delivered and full of quality information. Totally recommend this course.

Dr. Ahern was very clear and concise. Great lecture. Thank you!

Amazing lecture and slides explained very well and it was useful to have the slides downloaded.

I learned a lot about cell structure in the most simple and efficient way.

It is too much Helping. It is Awesome and helpful

I finally understood why keto diet is so effective :) Thank you Dr. Kevin!

The lecture were short and concise and were just thesame as what I needed to learn.

The lecturer uses great analogies to make concepts easier to understand.

This lecture was very educational, and well organised, moving from the basics to the complicated topics, explaining every topic step by step.

Explains everything extremely clearly and made all of the processes easy to understand. This was a great lecture series!

Excellent lectures. The professor speaks very clearly. He makes it easy to understand.

Every topic was clearly explained and I could understand them very well.

These lectures are good , but it needs improvement it should be more in details , and the actions are not mentioned in its orders for example first of all initiation then elongation finally termination ..

I don't waste my time going to any biochemistry lectures at my medical school because I know that Dr Cornwall explains all of the content more clearly, in more depth, in less time. I always finish her lectures excited for the next one!

Brilliant! I have always found these topics extremely confusing at medical school, but Dr Cornwall is able to explain them in such a way that they seem straight forward and easy. This certainly replaces lectures for me! If anybody is unsure about trying this course, they should definitely try it! Dr Cornwall is the best biochemistry lecturer I have seen!

Dr. Cornwall hesitates a lot, and seems unprepared and unsure. Make people feel like she is reading the material and even not familiar with the reading materials. It is really confusing.

Very helpful on understanding the basics of the repair mechanisms.

The Good: Lecture: 5/5 Amazing Lecture! I learned a lot! The Not so good: Quiz:2/5 Only 1 question....and was not as specific as I would like it to have been. Perhaps consider having at least 50% of the terms discussed included in the Quiz.

The best professor! He makes everything easier. Very good lectures.

The subject is really hard... but the professor is excellent!

A great lecture. I am a high school student and i struggle with biology. I get a better explanation from your lectures and I am not even a native English speaker. Thank you so much!

Thank you so much for beautifully explaining every single basic detail in chemistry. The modules covered up the required topics from the scratch to strengthen my basics.

Thank you Dr Ahern! Thanks to your clear and nice explanations With integrations I am finally starting to understand Biochem! You make difficult things look so simple and enhances the importance and intelligence of mother nature in our human bodies

Incredibly good! I have spent hours studying from the book and this is by far the most helpful in terms of deep,meaningful understanding of the subject.

I think this course is really informative, though I would like some more details in subjects like RTKs and G coupled proteins. And also please add English subtitles to this course! I'm not native and I found it hard to keep up!

I liked that she really knows what she is talking about and is able to explain complicated things with examples from everyday life.

I really could understand this lecture easily. Even the mid time of lecture gives questions are more helpful for interacting with it.

Great Job, I really enjoyed the lectures! very easy to follow!

Needs more substance. This was barely long enough to be an introduction.

This lecture and the one before are not so well explained. The clamp loader part and the process of semi discontinuous replication need more in depth explanation

Kevin must be the best teacher ever. He explains with a certainty only a person with many years of lecturing can. Simple, easy and fast, making complicated matters seem easy to learn. Compared to the slides i have in med. school, the content is the same. But this guy also gives the explaination in the same amount of time! His body language is also nice to watch as they are firm and open, kind of directing your thoughts, like a maestro. You just have to remember and do some repetition of EVERY detail he mentiones, it will for sure be on the exam. I also use his lectures to simplify my understandings from pdf files from school and heavy textbooks. I will recommend everyone to use this!! Also i love the quiz afterwards. 1rst year university medicine

it was really helpful,but a bit fast, good details and nice explaining

Fantastic lecture, just the amount of information I needed to cover and retain the topic.

It helps very much. Thank You. I will share with my friends.

Good clear concept review. Could use more specifics regarding cyclin and cdks.

Very clear summary. Would like to see more clinical correlations made.

few things are missing like discoiling of histone protien and a sentence is not repeates

Structurally complete, however, relatively outdated. Enough for medical study purposes.

Very good keeps on track with my textbook. Taking Intro Bio

great lecture! I still feel the need to fill in the gaps but it has given me an overview of gene regulation

It's very clearly explained and very useful for my studies. I would like it to be a bit more detailed but not too difficult.

Brief and comprehensive lectures. Really makes mechanisms and actors really to understand.

Dr Georgina is amazing. Thank you for making all these difficult concepts easier for us.

Thank you so much Dr Kevin, this lecture series are the best that I have seen so far and explain very well, simple and practical a very complicated topic.

he is so good ... I am very thankful to you sir !!

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!

Easy to understand with the structure of the molecule. Very clear and straight forward.

Presenter explains the medical relevant aspects of S-G disorders in a logical sequence.

Great series on the medically relevant aspects of diseases affected by genetics.

Great Instructor. Clear, concise, very easy to comprehend. Dr. Ahern gives the "meat" of the concept. Not long winded.

I subscribe because of this professor. Great lectures and explanation. Nice job

What I loved the most about this lecture was how Dr. Cornwall actually took her time to explain the concepts discussed, and even used simple analogies to ensure that the information was easier to digest. This is something you find lacking in many professional lectures. Thanks again Dr. Cornwall!

It was very clear and explained well- the subject itself is usually hard to explain

Thank you dr. Georgina Cornwall! Everything was perfectly understood with your lecture!

She spends half an hour explaining the steps of meiosis and doesn't even get into details... I'm not sure how she can manage to explain such simple topics in such a long time (it's half a movie time, for God's sake!). She should base her lectures on Molecular Biology of the Cell, by Bruce Alberts et al., AT A MINIMUM. Lecturio has many excelling lecturers; unfortunately, Dr. Cornwall is not one of them.

I like the Lecture it explain many things but there are very important thinks haven't been explained like how to knockout some genes by using shRNA or siRNA. I know that you explain CRSPR which is the greatest method ever . But I think is necessary to talk about shRNA, siRNA and what the advantage and disadvantag because everyday in school we here about them and I think they need to coverd in this lecture. Thanks

Don't replace her. Good OVERVIEW/REVIEW of the material at hand. Her pace is good. Her voice and expression and everything else is dynamic and engaging.

The professor was very clear and his tone was lively :)

Please replace her. Explanation is very poor, she hesitate a lot, and seems unprepared and unsure. It is confusing and in comparison to a lot of lecturers you have here, the standard is incredibly low!

Though it was good. Be patient w/ Imprinting the slides in Prader Willi/Angelman give a good visual of what it is.

I was impressed by the knowledge of the professor. However, the very short length of each lecture was disturbing and distracting.

Good lectures, would be more helpful if there are practice questions and further readings. - first year medical student.

this guy so good only amazing so much only omg nice nice

These lectures (all of medical genetics) was really useful in connecting your knowledge. It is great how general theory is connected to the most important genetic diseases - very useful

Great professor, great explanations. This video was like a summary of important parts.

it was very good lecture it will help me in my med biochem class thanku

Great breakdown of these biologically important macromolecules. Amazing detail on presenting each macromolecule and distinguishing polymers, monomers and non polymers.

She is very detailed but yet not overwhelming with the lecture. It's been great help on my bio knowledge.

Not very hard to understand, sometimes a bit too "shallow". However most often very good. Even great.

They are good..But lengthy..I will take take lecturio for my step 2 also

The professor was very knowledgeable and presented the information in a clear and concise manner

Exactly what I needed. Straightforward and to the point. Linearly organized.

Very helpful Keep it up .. easy to understand . Lecture in a simple way

Hello though I learnt new things by the good explanation of the pathway but I will be happy if there could be mnemonics to remember then easily. Thanks

The Dr Georgina did it very well she know detail about the subject matter andinet did not express about her and execelentroll model for me!

Very good explanation and notes and diagrams. Dr has good quality teaching .

I like the way the instructor presents the material , and the examples she uses.

The lecture covered everything I needed to know for my upcoming test. I feel so much more prepared now!

Thank you very much for such a great lectures!Biochemistry have never been so interestig until now)

Well, I love the way Dr. G explains, however, the lecture on cell control wasn't the best and needed more explanations and needed to be more simplified . I put five stars because Dr. G has helped me a lot and made Biology a fun course.

This course really helped me understand the cellular structure, I learnt more from one of the 20 minute lectures, than I did in a 3 hour lecture at university, so these really help!

Good and clear explanation, Dr. G makes it fun to learn biology.

The course didn't deliver the main message I was searching for. I hoped to find a more concise and direct material for each topic. The Genetic Course did not help at all for what I was searching. I was hoping for high-yield topics and a more direct delivery of the material. We have too little time.
