Are these good schools?

To echo the sentiments already expressed, the colleges you first listed - Indiana, DePaul, Purdue, and Marquette - are all very good schools. I personally attended DePaul and loved it. It's right in the Chicago, which, if you haven't been, is probably the best city in the US (ok, maybe not in the winter); the Lincoln Park Campus is gorgeous; the reputation is solid; and the social life is vibrant. An additional bonus to being located in the city is access to internships. Chicago companies recruit hard at DePaul, so landing one isn't too difficult. However, the other three schools are excellent as well. I would make your decision based on the strengths of each school, both academically and socially, and how these fit with your personal and professional goals.
