Hi there,
Thanks for posting. It sounds like you have a solid profile for reputable schools. The degree focused on statistics, and the investment bank experience, help you stand out from many Indian IT applicants as you have mentioned (not same as engineering or IT). The fact that you'll be gaining some US experience soon, and any international experience and exposure you have, will be a plus. What stood out for me was founding the Tech Consulting grp at IIT that sounds pretty successful... that sounds like the type of thing that would really give you some great experience you could draw from in your future career as well as in the b-school classroom so be sure to detail that more in essays/applications. You haven't mentioned your post-MBA goals here; just keep in mind that your overall 'story' is all relevant- why the MBA? why now? why THIS school? etc.
I wouldn't worry a ton about the 710 per se, though if you truly think you can improve you could try again as they'll take the highest score. But I would keep in mind even going in with a solid profile, those top schools (H/S/Wh) are so very competitive... it can be tough, and can come down to how you stack up vs other well qualified applicants. So you may want to apply to 1-2 top 5-8 schools for ex; then another few from 8-15 or 8-20, and maybe even a safety option in the 20-25 or 20-30 range. But do your research first and only apply where you'd definitely like to go! For more on choosing schools, check out our free download at:
