This is singularly the best investment I made for the first year of medical school. Each video is a jackpot of information with amazing drawings, great energy, and a phenomenal professor!

Currently, the only things saving my embryology and 1st-trimester ultrasound marks - keep the wealth of education flowing! Highly recommended!

I bought lifetime access because I believe there is no better source for learning the foundation of medicine. I strongly recommend him to anyone who cares about true learning and not merely memorizing!
