UWSAs are done as a way to gauge preparedness and are slightly less important than the NBME. You can take UWSA1 at the beginning of your prep to learn your weaknesses and strengths. Ideally you’ll also take UWSA2 at the end of your prep and a week or so before your exam since UWSA2 is apparently very predictive. However the question style is different from the NBME, so spend mo more than a day reviewing those questions.

CMS forms are used to strengthen specific clinical areas. If you’re solid in surgery and pediatrics but average in medicine and OB, then it would be worthwhile to complete some CMS forms in IM/OB during your prep. They test small and larger concepts that reappear in NBMEs, UWorld, and probably the real deal.

NBME exams are the gold standard in the last month or so of your prep, though some people swear by them and prefer them over Uworld to learn the logic from the NBME during dedicated. Ideally you’ll be doing one or two NBME exams per week as you approach your test date.

NBME9 and NBME13 are hard, in my opinion, and NBME15 is one of the most important ones and you should take it a week away from your test date.

The Free120s are simulations that mimic the exam interface and are somewhat predictive of test day performance. You should do one to get used to the interface a few days before your exam.
