For a top 10 MBA program it's common. Though keep in mind that that also covers my living expenses for being unemployed and living in NYC for like a year and a half. And for all the partying you're supposed to do while in school, I don't have any savings to cover any of it.
Also, most people that come out of these programs are making at least $100k right out the chute, so it's one of the few remaining American academic investments that really pays for itself.
What are you planning on going into out of stern?
