sorry, I am not in that area...but here is something that might motivate help...
I am not sure if you are using kaplan or any other source for your studyin...but kaplan has flashcars for OAT/DAT and they are useful to have around...you can study for your OAT at work, on the bus, waiting rooms, shopping...you get the idea...
its easier to just grab the cards and go sit somewhere nice in the outdoors and study rather than totally barrying yourself in the books...
obviously the flashcards are not intended to cover EVERYTHING...but they are really nicly done and helpful...
I devide mine into piles of MUST KNOWS (like formulas, etc.) and always keep those handy!
anyways...hope that was a bit helpful...flashcards are good when you are tired of the BOOKS!
ask people on the forum if they can sell theirs to you...I am still using mine...
GOOD LUCK!
