The summer is actually 2 half semesters - summer 1 and summer 2. Summer 1 is May and June and Summer 2 is July and August. You pay for summer semesters the same as any other except since it is a half semester you pay 1/2 tuition (as an example not real numbers - if a full tuition for a fall or spring semester is $10,000 - then tuition for summer 1 or summer 2 will be $5,000). You don’t pay any tuition when you are on co-op. So a typical school year might be - fall semester classes, spring semester co-op, summer 1 co-op continued and summer 2 classes. There is no saving any tuition by doing a shorter program - you still need 8 semesters of classes and therefore 8 semesters of tuition (unless you come in with AP credits) .
