Stomp On Step 1 is a free video series that prepares medical students for the U.S.M.L.E. Step 1 Medical Board Exam. This site is full of all of the things I wish somebody had told me before I took the exam. I know what you are thinking “Not another study resource! I already have way too many books and videos to possibly get through.” But this video series is as a time saver, not a time commitment. Since it is impossible to relearn 2 full years’ worth of medical school curriculum in the weeks leading up to the exam the logical thing to do is focus on studying efficiency. What sets Stomp On Step 1 apart from other study aids is the High Yield Rating. The HYR is a rating scale from 0 to 10 that gives you an estimate for how likely each topic is to appear on the USMLE Step 1 exam.
