Um, I used Barron's to study from, and I thought I did pretty good on the MCAT. I never really got bogged down by the number, name, etc of the materials I used to study from. AAMC II, IV, Kaplan, Barrons, etc. I actually used prep materials cheaper and older than Barrons. I used your theory--save the "best" for last. But I wasn't really motivated to study, and basically the Kaplan (or whatever the big fat book is I paid $60 for)served as a really authoritative paperweight because I never actually got to it. I found the best preparation for the MCAT was taking courses that prepared me for them. I have said this numerous other times, and no one really believes me, but I overloaded myself spring semester with classes because it "made me think smarter." I took literature, philosophy, and art classes to help me read and write better, I took advanced calculus courses to help me analyze better, and I took science courses where i knew the tests were similar to the MCAT. And I made sure to take the April MCAT. It was the best thing I ever did--I was completely in the mindset, and I didn't worry a bit. Honestly, you have six months to go. Don't worry about it for at least another two or three, but strategically plan your spring semester. Its just my two cents. And don't burn Barrons; at least sell it back to a used book store!
