I am doing early bird thing on Kaplan, and we started studying 3 months ago. Here's my opinion--I think the Kaplan MCAT is GREAT....we have all MD/PhD teachers, teaching different subjects depending on what they are good at. Last class, our teach stayed behind for two extra hours b/c we couldn't understand some concepts that we had learned ages ago. I suppose it all depends on the center in your city and the personnell in it. We also have extra video lessons, that we can take a look at to reinforce stuff. My point is--If you have TONS of time, and are able to use ALL of the Kaplan resources MORE than once (practise multiple times) I don't think you can go wrong.
I have also taken a look at PR stuff, and it seems to be missing some things that Kaplan has in their books, and vice versa. So, the more different kinds of books you have over each topic, the better it may be. I wish you well!!
