Imago:
I'll give you my two cents since you asked. I took the Kaplan course and watched all the lectures while following along in the review book.
I then bought a TPR book, you know the really thick one, Hyperlearning, that has a separate section for each subject and study that almost exclusively.
The best part of the Kaplan class was the full-length practice tests which I took every weekend before the MCAT. The TPR material is much better than Kaplan IMO and the topical tests that Kaplan has are WAY harder than the MCAT and not an economical use of your time. They require much more computation and indepth analysis than any question on the real MCAT.
The last two weeks I studied the note cards from Kaplan and took several more full length test.
For comparison, I got a 23 on my first Kaplan diagnostic and got a 11,10,10,Q on the real thing. That's not a stellar score I know, but trust me I'm no brain surgeon and only did that well through brute-force studying!
Best of luck,
Spang
