There’s also a difference in feel between the colleges. The honor code is really important at BMC which makes it less competitive among the students, and more cooperative. I don’t know how competitive the student body is among itself at Smith.
Smith, OTOH, is part of the 5-col consortium with free transportation among the campuses. If your daughter decides to take classes at Hampshire, MHC, Amherst or UMass Amherst and mabye do research there, she can do so.
