Duke-Fuqua, Rice-Jones & Cornell-Johnson, WashUStL-Olin & Ohio State-Fisher are worth investigating. I picked these schools based on a solid “employed at graduation” percentage of at least 80%.
Indiana–Kelley offers merit scholarships. University of Michigan-Ross should be considered. Carnegie Mellon-Tepper will like your GMAT score. Emory-Goizueta.
BU-Questrom is a great offer. If you are able to get a lucrative internship between the first & second years of the MBA program, then your need to borrow might be reduced.
UMass-Amherst-Isenberg is making a spectacular offer financially especially if you secure a solid internship.
Some specialty master’s degree programs offer scholarships. Most of these are 10 month programs.
It will be tough to beat your current scholarship offers, but if you don’t try you will never know. And it will be tough to beat Boston University’s location. I suggest BU-Questrom if willing to put in substantial effort in getting a summer internship.
