Buy the Kaplan book (sold at bookstores) or see if you can get someones Kaplan books and flashcards (I'm not sure but they might have more detail in them). I felt Kaplan was good for everything but the PAT.
Barrons dental school book is good. Maybe this is better for the PAT, though I did not use it for that reason, but I have heard that the PAT instruction is pretty good.
TopScore is a CD with 3 full length practice exams -- well worth it!
