achiever / topscore
science 18-20 / 20-22
PAT 18-20 / 20-23
QR 21-23 / 21-24
RC I didn't even solve this section.
<study materials>
BIO : I took only bio I and II, but not the higher biology such as molecular bio, microbio, genetics and etc. I think that's why I got only 20. I read Cliffs BIO, some chapters of Campbell and solved Destroyer just once. but bio is so broad and I don't think those materials are helpful. I don't know which materials I have to use for bio section. it's so random and broad. In my opinion, if you take higher biology classes, then you will be fine.
CHM : I used school note, Kaplan blue book and destroyer, I think that's enough. and no tricky questions.
ORGO : I really expected high score in this section because I solve all the questions in Organic chemistry odyssey from DR. Romano. and I inversted most of the time on this section because i thought it's the easiest section to raise up the score. I am so disappointed. don't use organic chemistry odyssey. i think kaplan and destroyer are fine.
PAT : I just took 3-4 tests out of 10 mock tests in CRACK. the scores were 22-24. I think crack is enough and it's very similar to real dat pat.
RC : Frankly speaking, I give up this section. I didn't even study becuase I thought it's the most difficult section that I can raise the score even if I study and practice a lot. I am a slow reader and english is not my first language.
QR : I just solved achiever and topscore, not destoryer. I am good at math, so i didn't spend much time on this section. In real dat, time was not enough. I couldn't even read the very last question.
<study hours>
I studied 10 hours for 3 months. I used achiever, topscore, destroyer, organic chemistry odyssey, crack, Cliffs bio, some chapters of Campbell.
good luck, SDNers!
