This course will fully prepare you for Step 1 of the United States Medical Licensing Examination (USMLE). It not only includes 90 hours of video lectures, but also USMLE test style questions which will help you identify your weak areas. The lectures are designed for medical students and doctors who are planning to work in the United States, or simply want to assess their knowledge by mastering Step 1 of the USMLE.

Renowned medical experts such as editor-in-chief of The American Journal of Medicine, Prof. Joseph Alpert, specialized histologist Prof. Geoffrey Meyer, and experienced hematologist Prof. Paul Moss, among others, will guide you through the learning process.

The course is structured as follows:
  • Anatomy
  • Histology 
  • Embryology 
  • Physiology
  • Biochemistry
  • Advanced Cardiology 
  • Advanced Vascular Medicine
  • Advanced Hematology 
  • Advanced Respiratory Medicine

More questions and video courses for the preparation of the USMLE Step 1 will be added soon.

Worth it

Very well done. Detailed. Great set of videos that covers all the information . Concept pages are fantastic. Good set of practice qs after the videos.

 
3D illustrious
von snehalkumar p. am 24. März 2024 für Development of Musculoskeletal System and Skin

Teaching embryology without 3D illustrations is a crime … at least on such a big platform.. Many of the lectures seems hurried just for the sake of finishing within 10 min .

 
response to your qns
von Lariat A. am 20. März 2024 für Membrane Physiology

while visual aids were pretty cool, the lecture was more of narration but not with simplicity and in-depth tutoring i am accustomed to. I was hoping for more variation, which was the reason i spent a little more time watching them. After a few, i concluded that it wasn't doing it for me. But of course, it was only a few topics i reviewed as i was busy with clinical rotations. thank you all in all.
