Thinking about taking classes this summer? CU Summer Session has hundreds of classes available to help you earn credit toward your degree. Summer classes provide you the flexibility to lighten your course load in future semesters or help you stay on track toward graduation.
Summer Sessions are staggered to fit your schedule and, if your summer unexpectedly frees up, registration remains open through at least the second day of the session (view session calendars).
