What are the GMAT math questions like ?

<p>Are they logic based like the ones on the SAT I or are they testing our real knowledge like the SAT II does ?I am curious because I am a really good math student, scored 800 on SAT II math lvl 2 subject test but totally bombed the SAT I math sections and only scored 710.I have to admit though that the curve was pretty bad and only got 3 wrong and in a way I wasnt lucky to score about 740-50 but anyway.I find these questions really difficult and desperately wanna score at least 720-30 on my GMAT which I will take at the end of my junior year to apply for the Harvard 2+2 program..</p>
