If anyone is interested in purchasing the Entire Princeton Review - USMLE step 1 Online Review Course (including online access + all texts brand new, still in original box) for hundreds of dollars less than the original price check-out my ad:
I have never heard of anyone using Princeton Review for step 1, but I couldnt endorse Kaplan if my daddy sold it. I bought the intense prep (online lectures, q-bank, q-book, etc.), but after taking the test I realized just what a waste of money Kaplan is. Hate to through another variable into the equation, but have you thought of using UW.
