The USMLE step 1 exam is a major milestone in the first two years of medical school that has major impacts on residency choices for MD-PhD students down the road.
A group at OHSU has launched a website with free USMLE review course on video that were very popular last year. The review course is run by a Michael Wilson. Dr. Wilson initially failed the boards (168). He then took a couple months to learn how to take the boards and got a 230 on Step 1 and a 256 on step 2. The course features free handouts and 50 hours of streaming video. For those of you thinking about the boards, worth a look at OHSUBOOKS.com.
