Gmat quant question

i dont know if that information is made publicly available by the GMAC, or if it even stays constant from test to test. as an example, in my practice tests i was struggling with permutation and probability problems. i tried to make a point to study those more heavily, but on my actual GMAT, i had 0 probability and 0 permutation questions, which was a relief. however, other people might have gotten at least a couple of these.

the other thing that throws things off is the amount of 'experimental / ungraded' questions in the quant. i think there's at least 5 or more experimental questions in the quant, and they can be about any topic, so it's hard to give a rough estimate.

i think if you study geometry, rate/work problems, absolute value, and number questions (odd/even, integers, etc), this would cover the vast majority of questions.
