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