It might have been more helpful to just make a poll about what people think about Kaplan vs. EK...
I used EK for general chemistry and found that in all of my practice MCAT tests, I tended to know the general chem really well and rarely missed questions in that area..
I used Kaplan for everything else and in retrospect after receiving my scores, am not sure their books were all that effective. I think the best thing might be to just buy the whole EK package for the sciences and verbal. There's something about the way EK writes practice questions that forces you to have a deeper understanding of the science, which then makes you a smarter and more efficient test-taker. If I could do it all over again, I'd buy the EK package, their practice tests, the AAMC practice passage items, and the AAMC practice tests. I think if you went through all that material over a few months, you'd be set.
