I guarantee you a degree from Drexel is not worth 160k versus Pitt. An engineering degree is a flat paying field. Just because a school requires co-ops doesn’t mean you can’t get work experience at any other school.
There are plenty of summer internship and co-op opportunities no matter which school you go to.
College worth is a personal question no one can answer. How much are you/your parents willing to pay for an education and why. Pitt is a great school. Personally, it would not be worth 160k to go to Drexel.
