Hi there! I take my boards the 26th and I have heard wonderful things about the Kaplan review books, but there's a problem, the newest one is $100+, and well just getting out of school I am still poor .. so my question is this: does it truly matter what edition I buy? I know they have changed some of the rules over the years, and I am up to date on them since they were drilled into our head before graduation, so I can skip over that part of the book. I mostly need strategies, questions, anything and everything to put my nerves at ease. -forgot to add, I have access to ATI and all of the practice tests (although I'm not too sure if I like the layout of it) and I have the Mosby's review book, but I have found some mistakes in it, and not too sure if I like it also.
