I took my first DAT Thursday night. I absolutely bombed biology, and was pretty much brain dead in RC. Without further due, here are my scores: PA 20 QR 21 RC 17 Biology 16 GC 23 Organic 22 TS 20 AA 20 (Skip this paragraph if you just want to know my test itself.) Overall, I didn't actually studied that much. I was not a science major in college (econ and math major). I have already graduated, and works at the performing arts, so I have weird hours, no real weekends, and have side jobs to support myself as an starving artist. I knew that I had to take the DAT at some point this summer, so studied a little bit on and off (definitely more off than on) since February. I took a long break from studying because I was so occupied by my performances until early May, at which I wasn't sure if I would be ready to take the DAT yet. Finally, 9 days before my test date, I decided to register for the test, and logistics turned out that the only option was 5/29, which was 9 days away. It was crazy, absolutely DO NOT recommend doing this. So moral of the story -- register your DAT early, folks! In the short 9 days (actually less), I tried to go through DAT destroyer (did not finish. up to #300 in biology, ~#100 for GC, and #200 for OC), and also did a few tests with DAT Bootcamp for science and reading (did not finish). It had been a while since my science days (4-6 years), so I had a lot of refreshing to do. I did briefly went through Chad's video on the topics I need for OC. Also read through Cliff AP bio, and supplemented it with random Youtube videos on whatever area I didn't do well on DAT destroyer. And I went over my biochem/physiology notes from college days. For PAT, I mostly used Crack the DAT. DAT Bootcamp for RC. I didn't spend any time reviewing gen chem /math/RC because my study time was extremely limited. Again, I don't recommend doing this, folks! OK, now comes the real breakdown: Biology: It was hard. Harder than DAT Destroyer. I had always done well in genetics section, but there were a few problems on the test that was like "huh?" Topics are quite random, but barely any physiology. I spent 70% of my time studying bio, yet I did the worst in it. Sigh. GC: Way easier than DAT Destroyer. Don't have much advice for studying GC. Just know the equations well, understand the few main concepts and you should be all set. OC: Chad's video helped a lot. Also study the mechanisms helps if you don't memorize stuff well. I memorized as least amount of facts as possible, and relied on mechanisms to find out my answers. Use unit analysis as a last resort tool. PAT: Crack the DAT. Also helps if you physically make some of the shapes and figuring out relationships between sides for TFE. RC: Can't offer much advice in them. English was my second language, wasn't a science major, and didn't do much science research. Most of my questions were S&D friendly, though my brain was dead when I was at my 3rd passage, and I kept reading the same line. Used a mix of "Question road map" strategy and "S&D" (mostly when I ran out of time). QR: As I said before, I didn't review this at all. Knowing my test now, I probably would have done some reviewing on unit conversions and trigs. Additional tips: Felt the DAT official practice tests were a bit easier than my real DAT exam, and my scores from the practice tests let my guards down a bit. Argh! So yeah. That's my summary. Still trying to decide if I want to take DAT again. Good luck guys!
