APerez114:
Q: Do you think that I have a realistic opportunity at any of the schools mentioned?
A: Possibly. Cornell, Duke and Northwestern are more in your range than Harvard, Columbia, Stanford, Penn, etc.
Q: Also, which are my chances of obtaining a scholarship with those numbers?
A: You never know, but I don't think it's very likely. There isn't an exact science to determining scholarship money like there is for admissions by merit.
Q: As my main goal is to work in IB, which other schools do you think that I should consider if my profile isn’t good enough for the schools listed above? I was thinking about UCLA, Ross, McDonough, McCombs, NYStern, Tuck
A: Yes, you should consider all of these MBA programs. They all feed into IB, though some of them are more regional when it comes to recruiting.
