It felt a lot like the NBMEs I took. In fact, the exam was much more balanced, subject-wise than previous exams I have taken. They didn't ask a bunch of weird, obscure facts (no rare parasites, not too many new drug questions). Lots of heart murmurs, and unlike UWorld where they tell you where the murmur is heard best - you have to place the stethoscope over all 4 areas and hear for yourself.
The most obscure, "new material" questions I got were all Behavioral Science-related. I had a question on Root Cause Analysis, and lots of ethics questions that required actual knowledge of healthcare law. Don't skimp on BehavSci!
I got a couple difficult anatomy questions (one LE injury I took a running guess at - I'm not a podiatry student!) But in general the anatomy is very basic. Know how to read abdomimal CTs and all neuroimaging! Know the brachial plexus and the innervation of the lower limb. I feel like the best resource for learning anatomy was UW. FA is way too cursory. But in general, with anatomy, I think they are just looking to see if you can keep a cool head and reason from what you know.
And on test day, you're gonna have to guess. My best advice is to always answer questions based on what you do know, not what you don't know. For example, if you have it narrowed down to answer choices A or C, and you are kinda sure A is right, but you really have no idea what C is, always choose A. Guess from what you do know. Never guess from what you don't know. They design the exam like this on purpose, because they know med students are anal little f*ckers. Oftentimes, one of the wrong answer choices is straight-up something they don't expect 2nd year med student to know about yet. They are dangling it in front of you as bait, trying to get you to bite. Always guess from what you know you know.
Bear out.
