I don't agree with DK94588 on the issue that 3 rd attempt is not worth unless its result is extremely high (750+).
IMO, any number greater than ur previous score must give impression to adcom that u didn't give up, tried and eventually found ur spot. Is it logically true? Besides, all the Universities - top 1-30, 31-100, say they will consider the highest score of the applicant. None of them mention about averages or low scores.
Maverick2008, I am on the same boat as u are. But wondered urs is 600 (q49,v25) but mine is 630 (q50, v25): don't u think there is something strange round off and round up?
Anyway, i suggest u to retake. Believe me u will be pleased to do so.
With High score on GMAT u ' ll (other things being equal)
1) may be accepted to top schools
2) feel satisfied at least personally. After proving u can also nail it.
3) feel urself confident.
We can be study partners. I am sure 3rd attempt will be the last
one.
