Well, the EK books operate on the assumption that they are review materials (which they should be if you've taken your prereqs). Basically, they point out what out of all the stuff you forgot from intro bio that you're going to need to brush up on for the test. Fundamentally you cannot get around memorizing for the bio portion of this test (or really any portion other than VR). As I was explaining to a pre-law friend of mine, part of what makes the MCAT difficult is that it isn't simply a test of logic like the SAT or (so I've been told, the LSAT)--it's a logic test whose questions rest on recalling information from multiple years of science curriculum.
