GMAT Strategy

Hi,

I took the MGMAT free practice test before I started studying a couple of weeks ago, and scored a 700. Since then, I've studied the topics I didn't do well in and yesterday took the Kaplan Online Practice test that came with my Premiere review book.

I scored 95th percentile Quant, 93rd percentile Verbal, but then it said 89th percentile (670) overall! Is that possible, it seems more like there's something wrong with the test. I only got a couple of questions wrong, and frankly I expected a much higher score.

Appreciate any feedback others have on whether they had success with the Kaplan tests or how realistic they are. The fact that questions had several type-os made me feel a bit better, but I'll be taking a MGMAT CAT test tonight to get a second opinion.

Thanks!
