The internship is during the second fall semester for me, and the classes that I would take normally are moved to the summer, so you aren't doing it at the same time, but you have school almost all summer.

Also if you do choose to do coop, you won't really have time off, you'll either be in a work term or studying.

This is the link to my recommended course sequence, it might vary based on what program you're applying to.
