I was wondering what people thought about those three big books by Kaplan. I started to read the physioology part of it and boy, are they condensed. I figured this out when I was doing the sometimes poorly worded questions at the end of each section. ARe they enough to be used as the primary source of review or do they require extensive supplemental studying for the boards (may be my school taught way too much detail, which I can't find in the books. This gets me relieved, that my school over-teaches us, yet, worried that the book is not detailed enought at the same time)?
