Honestly it was simultaneously very similar to them and also nothing like them at all. COMQUEST was probably closest. Lots of the questions were really straightforward, and there was an INSANE amount of micro. All I'll say is that you need to know micro cold because it could easily tank your score. OMM actually wasn't that bad, a few WTF questions but most of it was doable if you knew the concepts. I only watched the OME OMM videos and thought that did a really good job of preparing you. Lots of MSK anatomy, which was expected. Honestly the topic breakdown was probably really close to the percentages they give with the blueprint thing. Of course there were the "WTF COMLEX" questions but I really don't think anyone can study for those because they can come from anywhere, and there really weren't all that many of them. Maybe like 1 or 2 per 50 questions. Videos are long but you don't always need to watch the whole thing to get what they are hinting at, and the long stem questions are there but most of the time you don't really need the whole thing to answer the question. I hardly ever fully read stems though so who knows, maybe it will come back to blow up in my face.
The interface was the worst part. It was like puke green and it takes forever to go back and view your flagged questions. Oh and this test is definitely not 8 blocks of 50. It's essentially 4 blocks of 100 because you don't get a break until after 100 questions, lunch at 200, and another break at 300. Be wary of your time. The break timer starts right after you submit a block and your time doesn't roll over compared to USMLE.
As to prep it was pretty much all in UFAPS + OME OMM videos, but who knows maybe I dropped a 450 and my advice is crap lol. We'll see.
These people will hit 800 on the real thing or close to it. That's insane. Our class high was only like a 680 and that dude was close to 260 on his USMLE practice tests.
And the correlation was pretty much the same for us. Class average was about 75-100 points lower than the last few years with a 500 being like 90th percentile lol
