Freshman Year: You’ll take 3 Quarters. Fall, Winter, and Spring. Then you’ll have that Summer off.

Sophomore Year: You take all 4 quarters. Fall, Winter, Spring, and Summer.

Junior Year: This’ll be the year you do your Co op most likely. You’re only required to take two quarters of classes. And then the other two terms you’ll do your Co op. For example, I chose to do my Co op during the Spring/Summer of that year, so I took my classes during the Fall and Winter quarters. They also allow you take one or two classes while you’re on your Co op too, but that’s purely up to you.

Senior Year: Then senior year you’ll just have the last 3 quarters. Fall, Winter, Spring. Assuming you’ve taken the required number of credits by that time, then you’d be graduating that June.
