How popular are co-ops at Clemson?
Do many students go on co-ops?
Has anyone had experience with these?
Not having a student there I can’t answer your question but I did find a page with info on their site. You may have already read. But they have some good stats listed there.

Also reddit might be a place to pose the question where more active students will answer.
