Well guys,
Kaplan actually asked me to teach for the DAT even though i didn't take Kaplan's course (i got hand-me down materials and studied off of the books). I had a friend who taught the MCAT and they wanted me to instruct for the DAT. The problem with Kaplan is that they say one thing to get your money, and don't help when you need them (personal experience from MANY friends). If you can take princeton or get their materials go for it. Kaplan is decent, but the princeton materials are more comprehensive in my opinion.
