At least you have a terrific instate option. I can’t speak to the quality of the program although I’m sure it is fine. The Pitt campus is very different. It felt like a university city vs. a campus when we visited. Not a bad or good thing just different. It’s in a great area of Pittsburgh. Unlike many cities where venturing off campus put you in some shady areas Oakland is a very nice area of Pittsburgh. CMU is within walking distance if you with to visit there as well. Ironically my D is a ChemE at Purdue. We are Ohio residents and she chose not to apply to tOSU for the same reason as your son wants to go out of state. She preferred the campus of Purdue to the feel of Pitt but that’s a personal decision. She is a sophomore and is very happy with her studies, the school and the opportunities it’s afforded her. Good luck!
