Now that it's over, the main thing that really jumps out at me is that I wish I had time to go through uworld TWICE!! I went through it extremely thoroughly the first time, (5-5.5 hrs per 48 questions). Every single word of every single question should be studied, the wrong answers, the question stems, everything!! I felt like the step questions were essentially the same as world questions, they just had that one extra piece of info that world questions omitted to make you think.
A few of my friends had kaplan qbank and I looked at a few of their questions. I don't know if I just saw more of their obscure questions, but they were NOTHING like the step questions, and they had a bunch of obscure info that I've never seen or heard before.
And of course, make sure you go through FA multiple times. Every question I had on subjects like pharm came straight from the info in FA. If you can answer any question someone were to ask you from FA, then you should start thinking about something like pharmcards. Otherwise imho you'll be studying extraneous detailed info that's not relevant to step.
G. audio really helped (1.5 speed), I'm a slower reader so RR Path would have taken too much time. I'm sure that's a good source too if you have the time to really study a dense book like that.
Hope that helps
