Please understand that personal statement is THE MOST IMPORTANT FACTOR in admission consideration. You will get offer as long as you can justify why you need this degree from this University. I don't f***ing get why people just take gmat again and again even they already get 700. It's madness.
No one gives shit about high GMAT or high gpa as long as you pass a certain benchmark (I would say gmat 700, gpa 3.2). During my interview with KPMG xxx city in the US, the manager said to me that they had never and would NEVER hire someone with GPA 4.0 because they understand that for college students there are other shit that candidates should also take care of too.
I think you are one of the best applicants this year. Go for your dream school. Spend all your time on your essay. Remember, that's key in your application. Other stuff is just fu yun.
