Is it true that Manhattan GMAT CAT scores are inflated? Do their questions reflect the real GMAT? Yesterday i scored a 620 on their CAT and i am concerned if this really portrays my true score ??? Any comments will be appreciated.
Our scores are neither inflated nor deflated, but they do have a wider standard deviation than the actual test. (This is true of any practice test - any simulated test is going to have a broader deviation as compared to the real thing.)
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.
