DAT Destroyer for GenChem and Orgo.
DAT Math for QR.
Kaplan DAT for overview of everything.
AP Cliffs Bio for Bio.
That's it for the books I used.
Good programs are:
CrackDATPAT for PAT
TopScore for everything (most representative of real test)
Achiever for everything (very hard tests)
Videos:
Chad's Video for GenChem + Orgo
Those are all that come to mind, and probably the core study materials.
PS: I have 2012 DAT Destroyer + DAT Math for sale. Used it to study, and like new. No writing or highlighting. PM if interested in buying. In hand and can ship it to you tomorrow.
