After reading all the reviews about UW being a better indicator of Step 1 material, I finally took the plunge. I had done about 600 questions of Kaplan Qbank before I purchased UW and have been getting killed on the nit-picky details of the fascinomas that Kaplan loves. After doing about 100 questions on UW, I really feel it's a much more fair, much more to the first aid, step up, BRS phys/path level of testing on general concepts. They do say (Kaplan, that is) that 40-50% of the board is "general concepts", so my discovery that USMLE World questions seem to center on the concepts is encouraging. I'm not sure what the bashing of UW is about in the other thread, but I've found it pretty good so far. Don't let me fool, anyone....the questions are damn hard, but if you think about it for awhile using basic concepts, you can find the connection. That hasn't been my experience with 30-40% of Kaplan questions. In case anyone is on the fence about UW, like I have been for the past couple weeks, I thought you'd like another opinion.... Good Luck All!
