To enroll in classes, students use CU Boulder's online registration system. They do not need to be on campus in order to register. Students can enroll in classes during the following time frames:
- Their assigned enrollment dates
- The schedule adjustment period
- The open enrollment period through the add deadline.
Students can find their enrollment dates in their Buff Portal. We encourage students to register for classes as soon as their enrollment dates begin.
Registering for classes is a lot like shopping online. Students can search for classes and build their shopping cart using one of two systems: CU Boulder Class Search or Buff Portal. Learn more about instructions for class searches and enrolling in classes at the Office of the Registrar’s website.
