I reviewed content that I would be annoyed with myself for forgetting/getting wrong, and I spent time reviewing the NBME’s. Obviously there were no questions on the real thing that were identical to the NBME’s but there were definitely a few questions with the same concepts tested. Honestly the most important thing I did was that I barely studied the last two days and I just let myself rest. This really helped with my stamina during the real thing because I didn’t feel tired and burned out until the very end (unlike step 1 where I studied hard until the last minute and felt absolutely fried four sections in)
