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!

Dr. Najeeb Lectures are top notch. Comprehensive medical lectures of the utmost quality across all preclinical (and many clinical) topics. Fantastic for deepening one's understanding for clinical practice and licensing/board examinations.

Dr. Najeeb is the single most spectacular medical teacher you will ever have! I love this man. He has clarified everything from the coagulation cascade, immunology, neurology, and embryology. His sense of humor and brilliant illustrations make everything stick well in your memory. His ability to illustrate 3-dimensional relationships has been useful for excelling in anatomy. I cannot thank you enough for all the wonderful work you do. I recommend your lectures to anyone who wants to truly understand medicine!

I'm grappling with my online studies in Infectious Disease at London School of Hygiene and Tropical Medicine. It's made me realize what a visual learner I still am. So these vids are making what was murky crystal clear. While I am easily distracted when I have to do hours of straight reading, I am glued to the videos. I've looked for a series of such videos for months. A million thanks - Dr Najeeb has a true passion for teaching and can convey highly complex topics in an understandable and fun way.
