Are you kidding me! I just spent the last 30 minutes writing my entire perception of how the real DAT was and when I submitted it didn't go through. Anyway, I'll hurry through it again... Also, I studied Kaplan Blue Book, flashcards, online material, and took the class (pointless). Topscore pro and the DAT Destroyer.
Bio - I dont know if there is anything that will prepare you for this unless you have a photographic memory and can learn everything in your andvanced bio books. I wanted to cry after the first 3 questions. Definitely more conceptual than the prep materials.
Gchem - I felt prepared for this but there were alot of questions that weren't on any of the prep material. I am quite dissapointed with my score, but I'm no chemistry scholar (my worst subject). And yes, I believe I had less than 5-6 calculations (its all a big blur now)
Ochem - Pretty straight forward. The Destroyer nailed it, although once again, there were a few questions that I never saw in any prep material.
PAT - Honestly, I wasnt prepared for this. I only say that because TopScore and Kaplan weren't nearly as difficult as the real DAT. The angles were ridiculous (less than a degree off, no joke), and some crazy folds in hole punching. With that said, I was confident going into this section. You really have to figure it out on your own, find mechanisms that work for you! (and not how other people tell you what to do)
RC - Alot of inference and tone questions. Other than that it is what it is.
QR - I felt that all of the prep materials were beneficial in preparing me for this. Once again, there were a couple of problems that threw me off.
