Bio - Cliffs AP Bio is a great start to reviewing, clear up any mistakes you have with your class textbook (I highly recommend the Campbells book), then clean it up with Destroyer.
GChem - Again, the Cliffs Chemistry book is a nice review. I also liked the Kaplan BB, but I think it was the Kaplan practice tests that were the best! The Destroyer is a little overkill in some people's opinion, but I always feel its better to be overprepared than underprepared. I personally went from a 16 to a 22 in the GChem section using the Destroyer after studying with Kaplan the first time.
Orgo - Nothing else but Destroyer! It has everything you need. The "Road Maps" are priceless!! Kaplan BB is also a nice side piece, but Destroyer was on the money for this section in my opinion.
PAT - Crack DAT PAT and nothing else! I felt it was identical to the test, maybe even harder than the actual thing which was good. I was scoring 18's and 19's but got a 20 on the real thing.
QR - I used Kaplan, but also some SAT books believe it or not. Get used to not using a calculator and learning tricks on estimating, practice formulas, etc, etc. I believe there is also a MATH Destroyer which I haven't used, but some of my friends have and they all said it did well for them, none of them scored less than an 18.
RC - I don't really know what to recommend for this section. I would say practice different strategies, there's "search and destroy" where you read the questions and then look through the passage, but I prefer reading the passage and making bullet points while reading so you know where to refer to in the passage. "Tone" questions suck, and the vocab isn't bad at it.
Good luck studying!
