Hey- I took DAT in June 2006 and bought Barron's with the intention of using it as a study aid. *WARNING*: Barron's is FULL of errors in ALL sections! (especially science). Luckily, I noticed this BEFORE I started to rely on it for studying... If you were going to use this book for anything, I thought the information at the front about applying and personal statements was best, and maybe the PAT practice was useful, but aside from that, this book gets a 👎 from me. Go for Kaplan!
