Hey
izulmanWhat an interesting profile! Thank you for all the detail. Looks like you have some great academics and also a really nice history of professional accomplishments. These will serve you well in the b-school process.
So to answer your GMAT question, of course a higher GMAT score would be helpful here if you are truly targeting the Top 10. Have you considered INSEAD at all or are you set on a US MBA? Maybe take a look at INSEAD, Stern, Johnson too. You seem like the type of candidate where we'd have a lot to chat about -- I think you'll get a lot out of a free consultation. See the link in my signature and please set one up when you are ready. (You don't have to wait for me to be available...just select the appointment slot that best fits your schedule.)
I hope that helps!
