i think QR section is all about practice and knowing what type of questions they will ask. Go to the library and check out all DAT prep books, and they generally have an overview of the material covered. Make sure you know your trig and methods of solving certain word problems (some word problems such as the good ol' age problems are some of the ones you must know how to do). Practice algebraic manipluations and stuff like percent conversions. I felt TopScore had a good QR section, so you should definitely check it out.
