UWChemE- that's exactly what I want to do, but U Chicago hasn't said anything about a visit weekend yet, and I'm waiting on accepts/rejects for the others. Missing classes isn't a big deal, I completed my credits early, and I'm doing only extra courses and my thesis now, the issue is money! I think I'd need at least 3 schools before I can visit. As I said, I want to make as informed a decision as possible.
Do you by any chance know how the theory profs are? I've been looking at Cui, Yethiraj, and Skinner.
