@crepes Many colleges offer optional coop, primarily in engineering but also in other majors. Based on posts here on CC some students have hesitated to do it because they will miss their friends and wonder how they will "make up’ the courses that they miss while on coop. Also some have reported limited assistance in landing a coop job at these coop optional schools. This is not the case at the coop schools you mentioned because the curriculum and campus liife is designed around coop.
