Kaplan CAT's- Accurate?

It is NOT true that our scores undervalue by 100 points. Our tests are as accurate as we can make them! That said, no test-prep company has a perfect test-day simulation. You can take the official GMATprep tests from www.mba.com for an even more accurate assessment of your score.

In the end, though, even those mathematically accurate test won't necessarily tell you what you need to know. Test Day is Test Day. Many students find that the pressure of the "real thing" kicks them into high-gear and allowing them to out-perform their previous best scores, but some unfortunately find that they haven't quite mastered the stress-management strategies they need despite exemplary CAT scores.

In the end, what's more important is that you use your CATs as a rough guide of your progress, and as a tool to identify your personal strengths and weaknesses. Don't be obsessed with your practice test scores--just go in to the real test calm, confident, and ready to put forth the best test-performance possible.

Hope this helps!
