just took the DAT this morning. there were three questions concerning lab methods. one was with H NMR, one with polarity, and one with infrared spec.
the biology threw me way off. i didn't expect to see some of the questions that were on there. i'd go as far to say that 40% of the Biology wasn't covered in the Kaplan book. luckly, i remembered most of it from class...schweeeew!
the PAT was also a little more difficult than topscore and kaplan (i know, i might as well said "blah blah blah"). i actually thought the keyhole and top/ front/side projections were fairly easy. the angles were tough...very very close.
for what it's worth, my advice would be to study everything thoroughly the best you can. the test is different for everybody. try not to anticipate too much based on word of mouth from recent test takers. i anticipated from 10:30pm-6am last night into this morning as i was unable to sleep. worst feeling i've ever had in my life. don't do it, it's not worth it.
keep studying. take the test with confidnce. you'll make it through! life is good at the end of the tunnel!
