Online summer courses provide the dynamic experience of a traditional class with the flexibility of a web-based environment. Most of your interactions with the instructor and other students will be online through CU Boulder’s online learning management system, Desire2Learn (D2L). Each online course is unique and may contain any combination of assignments including reading, writing, online quizzes, and discussion posts.

It takes 48 hours from the time you enroll in an online course before the course will be available to you on D2L. If you enroll in a term-based course, you will have access two days before the course start date.

State Authorization

The University is authorized to offer online education to prospective students residing in any state, however some restrictions still apply. Learn more about current restrictions.
