Hi yash321,
While a 650 is a strong score (it's just a bit shy of the 80th percentile overall), not all 650s are 'equal.' Many Business Schools view an Applicant's Quant Scaled Score as an indicator of how that Applicant might handle the 'academic side' of the Program, so a 650 with a higher Quant Scaled Score might be viewed as 'better' than one with a higher Verbal Scaled Score.
You're ultimately asking Admissions questions though, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile. There's a Forum full of those Experts here (and you'll have to provide far more information on your Overall profile):

If you choose to retest, then we have to examine how you've been studying. Once you've decided on whether to retest or not, you should post back here (or you can PM me directly) and we can talk through your study options going forward.
