I think DAT Destroyer was just fine for the math. While its strongest point is definitely the science sections, it also covered a wide array of math topics which appeared on my DAT. Kaplan and Topscore were also good practice for additonal help. Basically, the math section on the DAT is very unpredictable and preparation from any source out there is a good idea - kaplan, topscore, and Destroyer. They are all good for math - but Destroyer really gave me the extra edge in all the sciences.
