Are MGMAT CAT Scores inflated? If yes by how much?

The real test has a st.dev of about 30, which means if you score a 650, you can expect to score between 620 and 680 if you keep taking the test. Our test has a st.dev of about 50, which means if you score a 650, you can expect to score between 600 and 700 if you keep taking the test. So we're fairly close, but not as accurate as the real thing (and, frankly, I think a st.dev of 30 is too wide for a test on which the schools place such importance... but we've got to live with it). We continuously work on the test to try to narrow the gap, but I'd guess the closest it's even possible to get is about 40.

So, we're pretty close to the real test... but no one (including the real test) is close to an "exact" score b/c even the real thing has a range of 60 points.

I think a combination of our CATs and GMATPrep is a good one for practice tests. The GMATPrep b/c it's closest to the real thing, and ours b/c we actually give you explanations for the answers. Anytime you take these, though, I'd take the full test (including essays). Stamina is an issue for a 4-hour test - you have to practice that too.

Also, IF you get a 99%ile in verbal, then you can get away with a quant percentile in the 60s and still get around a 700. Then, obviously, if the verbal drops, the quant has to go up to compensate.
