I agree with topdent1, Kaplan's hole punching is far easier than the real thing. I was getting 100% on that section for Kaplan, suddenly the real DAT there are 6 holes punched. Wasn't prepared for that and my mind went blank, not a pleasant experience. Somehow I managed to do well on the PAT, similar but slightly below my top Kaplan scores, but I think it would be wise to practice with other study materials so you don't come across something that completely surprises you.
