I took both a CAT practice test and the "official" GMAC practice test (the one that's available on mba.com). I scored 690 in both tests. However, at the CAT test approximately half of my answer choices both in math and verbal were wrong. When I took the GMAC test, however, I only had 11 wrong math problems and only 7 wrong verbal problems.

Can you help me explain the difference?

Thank you

Alex,

I've forwarded your question to Chris Ryan, who is our Director of Product and Instructor Development. He has the best handle on how our CAT works and should have some insights as to how to answer your question most accurately.
