I've been following this thread too, and I feel like somewhere along mid-summer the test took a turn for the freaky - I took it yesterday and am only now snapping out if my "wtf" haze.
What I mean is that I had a ridiculous amount of "what are you talking about?" questions, one so far as to having a list of farm animals for answer choices. My test was SUPER stats heavy and it was a good thing I re-looked up some of those equations during the break and wrote them down on my board like some had suggested on this forum. There was also a whole lot more psych than I expected, so brush up on all the yummy drugs and the good old DSM, my friends.
I studied my weaknesses (primarily cards, renal, and all those tricky endocrine disorders) the heaviest, and was disappointed to see so little of it on the exam. Lots of pedo immuno and OB peri-labor stuff, a lot of those pseudo-ethical "how do we best prevent systems errors in the hospital setting" type questions where any of the answer choices would have worked, and it's hard to know what NBME is thinking in terms of what's best - I'm sure USMLE World and the editors of Secrets will be updating their reviews with this stuff soon as it looks like NBME is pushing toward this realm.
In sum, I guess the test just really didn't focus on the bread and butter stuff that people generally say it does, and it felt more Step-1ish in terms of randomness and not being at all straight forward. It is frustrating that I could have failed, or could have done really well, and I honestly have no way of subjectively gauging it. I guess my advice to those taking it would be to be prepared for anything; I think I mistakenly bought into the hype that Step 2 is much "easier" and more straightforward than Step 1, which in my case did not turn out to be true at all.
