Hi. I've been studying for the GMAT, which I plan to write on April 30. I took one of the simulation tests on the POWERPREP CD-ROM and received 680. Two questions:
(1) Why was the percentile ranking of my overall score higher than the percentile rankings of each of my individual quant and verbal scores?
(2) Are these simulation tests representative of the real ETS GMAT?
I would appreciate any information that you can give me,
Sorry for a late reply, i will be brief
1) Your cumulative or combined percentile score is relative of the rest - that means that this particular percentage of people scored below you. However, due to the fact that any people are either good in Verbal or in Math, a good ballance (above 550) score is usually higher percentage-wise than each Math and Verbal Individually.
For example, I got 92% on math and 96% on verbal, but combined was 99% overall. This is because a lot of Math folks get high Math but not verbal and vice versa.
2) PP was representative for me. I got 730 or 740 just 24 hours before the real test and got 750 on the real test. Some say it is easier.... but not much if you were not familiar with the questions.
If you don't panic on the test, you should do within 20-30 points - this is a standard GMAT error - 27 points.
