It's done! I'm so relieved. Overall, it felt easier than I anticipated - for me, it felt easier than UWorld, harder than NBME CBSEs, and actually fairly comparable to my school's NBME organ block exams. Probably about 5% of the questions I just had no clue on, maybe 10% I was completely sure of, 10-20% I narrowed it down to two/made an unsure educated guess, and the bulk I was fairly but not completely confident of. Which is pretty much par for the course for me. There were a decent amount of questions that I knew specifically from UWorld; a few questions also looked familiar to me from previous practice tests (though I don't remember which ones). There were some topics I was (pleasantly) surprised to find had relatively few questions or were not tested in a ton of depth like I expected them to be. There was a pretty even mix of longer questions and shorter questions, as well as first order and higher order.
Tip for test day - these worked for me, but are probably a matter of personal preference: If you have time left at the end of a block, it gets added to your total break time. It usually took me 40-50 minutes to finish the block, so in my leftover time I would get up, leave the testing room, and walk around, drink my caffeine, or eat a small snack. Usually I just power through as long as I can, but this was REALLY helpful for me to not get fatigued/unfocused so I'm glad I did it, especially because I was feeling a little tired. To maximize break time, I highly recommend wearing clothes with no pockets, short sleeves, and shorts/capri-length pants to make the check-out/check-in process go more quickly. They check your pockets and ankles every time you come and go otherwise, which can get time consuming. Finally, you are allowed to bring notes/books and look at them between blocks. I brought FA along in case I felt like I wanted to give myself a quick refresher between blocks (which looking back...sounds kinda dumb but I was a nervous wreck lol) but found myself basically just checking my answers from the previous block, which was demoralizing if I missed one. I ended up putting the book in my car after the first break and started trying to clear my head/forget the questions after each block, which I think was better for me in terms of mental stamina, and also in terms of anxiety until we get our results because I won't be able to look up stuff I missed over the next few weeks.
For posterity, I used pretty much UFAP + Sketchy + a little BRS Physio, using the Bros deck to review the more memorization-heavy topics in FA and taking weekly practice tests during dedicated. I also used some other resources (Goljan, Costanzo, Kaplan qbank, Rx qbank) throughout my school's organ systems but not during dedicated. Without having my score back, I'm not sure at this point if I would have done anything differently. The majority of the questions were at least familiar to me, it was just a matter of remembering it.
And my practice test scores - shooting for a 210-220ish
~7 weeks before: CBSE w/ no preparation besides classes - 176
4 weeks before: UWorld sim 1 - 196
3 weeks before: NBME 18 - 190
2 weeks before: NBME 19 - 205
1 week before on same day: free 120 79% and Uworld Sim 2 180 (felt super distracted/anxious during this exam...advisor told me to take an NBME the next day before making a decision)
6 days before: NBME 16 - 213 (advisor told me to just go for it)
I'll update with my real score when it gets here. Thank you all so much for all the help and advice over the last couple days! I was really a hot mess in terms of anxiety and you guys were all so encouraging and supportive - it was really helpful. Wishing the best to all of you guys!
