99 percentile is good; however, the 800score.com test is not a particularly good test. You can do a search on this forum to find other posts about it so don't put all your faith in that one test. Take the GMATPrep cat, which is recognized as the best predictor for the real GMAT and see how you do.

Hi ,

Thanks a lot for the reply.. I took the gmat prep test nd it showed a score of 680....is that good enough.. as in how much improvement can be acheived over the next 45 days or so.. if this is my staring point....
My individual scores are :
Quant : 37 Questions 1unattempted 14 incorrect
Verbal : 41 questions 1 unattempted 14 incorrect

FYI :Am looking at the top 20 B schools

680 on the GMATPrep as a baseline before prep is a great score. The amount of improvement you can achieve varies greatly on your own talent and study prep. If you look at my signature, you'll see the range of cat scores that I achieved during my prep.
