You're better off with the white book that the KAPLAN course gives you. I didn't take their course so I bought the blue book from the bookstore. I went through everything in there--front-to-back, back-to-front and then my friend gave me his white book he got from taking the course and I did the same thing with it. What I found was that the only minor difference was 1)the white one came with more practice questions after each section 2)there was a lot more information about plants on the biology section in the white one than there was in the blue (which you will definitely need to know for the DAT). You're fine without getting the blue book sold at the bookstore, but if makes you feel more comfortable about taking the test, go for it.drdoodle said:Any difference between the Blue Book and the book Kaplan gives you when you take their classroom course? Just wondering if I might have been better prepared for the exam with the BB than the other one.
