Query: An important element for GMAT review

I scored in the 700s on the big test, and relied on 3 resources: Kaplan GMAT CD ROM, A+ Notes for Algebra by Rong Yang and the Official Guide by ETS (DO NOT GET THE FLAWED SOFTWARE -- BUY THE ETS BOOK).My focus area was math, having not taken a math class in 8 years, but those 3 resources helped me get me where I wanted to be. Be forewarned, the Kaplan CD math questions will game you. The questions on the real test are more straightforward, and don't try to trick you with units as often as Kaplan does. So don't be discouraged if you score a 570 on a Kaplan practice test with poor Math scores, you can probably add 100 points. But that's my experience -- let the poor score scare you into more study!I was probably ready for the verbal portion without much review. If your weakness is Math, as mine was, those three resources worked for me. I found Kaplan's timed tests and quizzes to be very helpful.But study you must, young Jedi.
