I agree that foreign students are above the average level of American students, generally speaking. But in this particular case? I had never heard of Babson College, and I'm pretty sure top students in any of the mentioned countries wouldn't choose Babson.

You probably never heard of them because they didn't go to your area to recruit. When I was looking at schools recruiters were coming to the school practically everyday. Some were bundled up in the same day.

And you never know why a student chooses a college until you ask. They might be offering something in their major. They may know an alumni who can get them a spot (with the proper grades of course), or they might offer more scholarship money. If you're family income is $200 a month are you really going to turn down a free education?
