I'm itching to find out why you applied to those schools (ASU, Rochester, etc.) knowing that you didn't really want to go to them. But I'll leave that alone for now...
Not knowing much about your profile, I would bet good money that your GMAT was *not* the reason why you weren't admitted to your favorite schools. Your GMAT score was good enough to get you in anywhere. If I had to guess, it was probably a lack of differentiation from other candidates. As I've said on this forum many times, male Indian applicants have a really hard time standing out (and thus gaining admission), at least when it comes to American schools.
I would recommend focusing on ways to set yourself apart from other Indians with tech backgrounds. I bet they all also have 700+ GMAT scores. Bumping your score from a 710 to a 750 won't make you any more attractive to b-schools (trust me on this), but showing how you're unique will!
