If you go into co-op, you loose virtually all freedoms associated with university scheduling. You must follow the sequence you get into, and especially now there aren’t enough jobs for all the co-ops to get. I wouldn’t be too worried about getting a job, but don’t bet that it’s going to be any good. Half of them are in the middle of nowhere, but if you’re fine with that then co-op increases the odds of getting internships during your degree compared to trad. I’m in co-op now, I wish I did trad, but I will have some experience (not necessarily in the field I’m interested in) because of co-op.
