You have a lot of flexibility in how you arrange your program. I started out planning to do 4 years and 1-2 co-ops and ended up with 5 years and 3 co-ops. I’ve had friends do everything in between. Doing 4 years and 2 co-ops means only space for 7 semesters of classes, so it’s a lot easier to do with AP/IB/dual credit coming in.
By staying for 5 years in something like CCIS, you have a chance to get a variety of co-ops to find what you like and also make connections with a variety of companies. A lot of employers in engineering/CS see co-op as a trial run for future full-time employment, so that can be a great foot in the door for great jobs as well.
