This man is obviously very smart but it is seriously painful to listen to ANY of his lectures. His stuttering is way to distracting.
All the necessary informations, briefly and easy to understand, nice as a review
It's too boring.. I found it less interactive, less interesting. Better to read my Gray's Anatomy book.
Used this to study for class and regular exams. Perfect.
