One thing USC has to offer that a lot of other schools don't is the football atmosphere. Campus is always dead on game day because everyone, and I mean EVERYONE, is at Williams-Bryce Stadium cheering on our Gamecocks. Also, USC is the #1 school for business and international business. Not Harvard, not Yale, but the University of South Carolina. You can make connections here that you can't make anywhere else.
