First of all, congrats for doing so well on the quant section. I am your evil twin, my quant has let me down on more than one occasion, but everything changed, once I got tutoring from Haakon Brown (Manhattan GMAT
) and Brent Hanneson . Brent especially, helped me frame my weaknesses and helped me mitigate them, which raised my comfort level as well. I ended up spending about 800$ in process, in the grand scheme of things it was well worth it. So don't throw in towel, GMAT is a beast and it can be conquered, but to do so you should try minimize your weaknesses (your Verbal/RC muscles may need more of the good stuff), because this beast pounces on any opportunity that you yield, be it Quant or Verbal. Additionally, the extra help can be in the form a friend as well, but he or she has to be someone who can not only tell you what you're doing wrong, but also how you end up choosing the wrong answer. You may also post your mistakes on GMC forums and let your peers tell you the why and how. Above all stay positive, because you can still take another stab at the GMAT.
Unfortunately, you belong to an over represented demographic (Indian/IT/Male) and its not uncommon see scores in excess of 740+ from your competitors (other Indian/IT/Males). If you're targeting top 20 schools then you may need to bring up that GMAT score to bolster your chances of getting in.
Good luck with the rest of your MBA application.
