HI,
I'm also a year away from taking the DAT. I'm going to get done with O Chem and Biology this year and then I'm going to study for a good 3-6 months. Unfortunately, I haven't been that successful in finding books for the DAT. I looked practically everywhere. I heard about the scholarwares program and that is probably the best thing on the market. Also, the other books like by Kaplan, have their strengths and weaknesses. So it will be must to mix and match. Also, I have heard from other people that one can use MCAT materials to prepare for the BIO, O Chem, and Chem parts; A math prep book; and verbal builder for the verbal part; and then comes the most unique part the Perceptual Ability (For this I think mixing and matching will be necessary from many books.) Hopefully in six months or so something new will come out and make our lives easier.
