Answer 2

You mean business schools? You can go to your local library and they have books that tell about all the colleges and rankings etc. They will emphazise what is best of each program and tell you more about student population etc. Newsweek also does a yearly ranking of top schools. Perhaps the library would have an old copy of this?

Best to you!
