Incidentally, one reason why Rochester has a higher admission rate than its peers is that many applicants to Cornell use it as their “safe” school. It’s all in the company you keep.
Also, some years ago, Rochester established a forward-looking policy where they offer a fifth year tuition-free if a student has earned a degree in a focused major (such as engineering) in four years, and wants a chance to broaden his or her education with the electives that couldn’t fit into the schedule. However, their school ranking took a hit by organizations that look at the percentage of students who graduate in four years. I don’t know if that’s still the case.
Upshot: numbers aren’t everything.
