hello, i am a post-bacc student. i just completed 2 semesters of chemistry, and nothing else. i would like to use the summer to begin studying for the mcat so that i can get my feet wet for future courses and because i don't have anything else to do this summer and don't want to lose what little intellectual inertia i have. i'd like to buy a review book, and i'm probably going to buy a used one. i've read the opinions here about kaplan vs. examkrackers vs. princeton review--does anyone have any advice to give me about which one might work best for early learning/review? thanks for your help--good luck everyone!
