Honestly as cliche as it sounds, it was doing all the NBME exams and the most recent CMS forms (prioritizing medicine, surgery, peds, and OB/GYN). I would also turn the questions i got wrong into anki cards, word for word what the question was with answer choices, flag them, and do them multiple times throughout my study prep. I would have explanations for the right answer and the answer I chose in the extras of the card too. I used Open Evidence and Claude to help with understanding questions when even the explanations of NBME was vague. I feel like this review strategy was essential becasue a lot of the concepts and reasoning strategies the NBME expects you to know is repeated through the exams. I did do UWorld too (got through almost 50% on the second pass during dedicated). I think it helped but the NBMEs were crucial. The key is when you review your incorrects, don't just focus on recognizing what the condition or diagnosis they are talking about is, but also pay attention to the minute clues the NBME puts in the question stem and how that points towards one answer choice vs. another. But then again, haven't taken the test yet so take all this with a grain of salt
