GWU is a great school in an incredible city. Many opportunities for internships, helpful faculty and the coursework in the business program is more challenging then anticipated. Do not get caught up in the myth of mostly "snobby" students.
There are tons of kids from elite private day and boarding schools. There are tons of rich kids driving BMWs, Mercedes, Range Rovers, and Porsches.I would say that if your parents are not brining in more than 500k after tax, you are going to feel very uncomfortable here. Also be prepared to drop a lot of money on keep up clothes-wise and shoes-wise.
Best choice I could have possibly made! Sure, there are plenty of spoiled rich kids whose grades certainly did not get them into GW, but there are also plenty of "real" people who are genuinely interesting and fun. Plus, DC is the BEST for college students.
