Okay so here is my breakdown of what I did...
I started studying at the end of may and stopped essentially 2 days before my test besides formulas and a pat test from CDP. Took the 2009 ADA test, Kaplan test (waste of time, their questions are taken straight out of their book), and problems from DAT Destroyer and Math Destroyer (Buy it! the best spent money of my entire prep materials), and cliffs ap bio. I probably studied 800 hours this summer, averaged 10 hrs the last 2 months, and 6-7 first month of studying.
Besides background review of the information DAT Destroyer is literally all I used to practice science problems. A lot of people say it is overkill but honestly "over preparing" so to speak is better because when you get to the test the problems may seem like a breeze compared to the difficultly of problems you practiced with. For Bio, there were only about 4 problems I was unfamiliar with, the other 36 I had encountered in the destroyer (again, don't just do the problems and move on, really read and understand every explanation in the back because they are GOLD)
Math (can't say much because I only got a 19... I had less than 2 min to go and 10 questions left, spent too much time on a few problems combined with the fact that the calculator is absolutely terrible, lags and no matter how many times you press clear everything and memory clear, it kept carrying over past calculations. But every problem was similar to those presented in Math Destroyer and a little easier!!! I did all 13 tests multiple times until I was familiar with the problems
RC: everyone test is so different and I just got lucky and had 2 easy science passages and 1 hard science passage, so didn't get any tone questions. I used CDP to prep, didn't do too much prep though.
PAT just used CDP; keyholes were more difficult because the test focused on small differences in proportion, TFE on par I would say for my test, ANgles: i thought I got most wrong because it was actually HARDER than CDP 2 angles always looked the exact same and the next 2 looked the same, so i guessed a lot, hole punches easy used tic tac toe method only a couple of hard ones that I worked through, Cubes, easy except 1 arrangement in which I could not tell if there was a cube there or not, it wasn't an illusion but definitely debatable if there was a hole there or a cube, and pattern folding, odd shapes, more so than CDP.
I think the hardest thing was actually getting the timing down. Started my review for PAT mid-summer, and with a month to go, took a practice CDP test every day/every other day and reviewed mistakes.
anyway hope this helps!
