Coming from a highly competitive pool,your GMAT score is too less for the schools you are targetting.Also what's ur GPA?
No idea about Maryland.
I would have a 650 at least for Maryland - still a competitive school to get into.
Guys,Thanks for the response.I gave some more thought and decided to take out
University of North Carolina--Chapel Hill (Kenan-Flagler),Georgetown University (McDonough) & University of California--Berkeley (Haas). Any pointers on other schools i can target?
