Anki, Uworld, Pathoma, and Boards and Beyond. The ultimate square. Other people posted the resources, but REMEMBER, that your Step 1 score is no longer that important, but now your CLERKSHIPS are even more important. Know everything you can and study until you can’t anymore. Your attendings in year 3 do not care what step is, they expect you to know everything regardless. The Shelf examines do not change. Kill step, and impress the attendings with your massive brain.
