agree with vlad - check out the various debriefs of the resources that top scorers used.
i have the kaplan premier
and kaplan 800
books. in my opinion, kaplan
, along with princeton review
, is good for earlier stages of studying when you want to get into some questions and just get used to writing GMAT style questions. however, since the questions are written in a style that vary in consistency with the gmat, i would spend less time on kaplan
later in your study period, and ramp up on official guide questions.
also, the kaplan
CD CAT scoring is a bit skewed from the actual algorithm, so ppl usually score 50 points lower on kaplan
CAT's which can be discouraging to some.
