Current Degree-Seeking Students

If you're placed on an academic suspension at the end of the spring 2023 semester, you can still register for Summer Session through CU Boulder Class Search prior to receiving the suspension hold. Once your summer coursework is complete, if your CU cumulative GPA increases to 2.0 or higher, you may contact your dean's office to reinstate to good academic standing.

If you were previously placed on academic suspension, you are eligible to enroll using the Course Request Form.

If you are on academic suspension, contact or 303-492-5148 for questions concerning registration. All other degree-seeking students should contact the Office of the Registrar at or 303-492-6970 for questions concerning online registration.

Current Nondegree Students

If you're thinking about applying to CU Boulder as a degree-seeking undergraduate student in the future, you may transfer an unlimited number of credits taken as a nondegree student on any CU campus; however, the applicability of these credits toward degree requirements is established by individual schools and colleges. Consult the dean's office of the school or college you plan to enter for further information.

If you enroll in summer classes and then change your mind, you may be assessed a financial penalty for the classes you dropped. See the Withdrawal section or call Continuing Education at 303-492-5148 for more information.

Follow the step-by-step instructions on the Office of the Registrar website to search for and enroll in classes.

If you are registering for a lecture class that has a required recitation and/or lab, the system will prompt you to add that component.

If you would like to take an independent study course or register for thesis or doctoral dissertation hours (900-level section numbers), you must contact the department for permission before you can enroll. Enrollment in these courses is limited by each department.

You have through July 12 to register for independent study coursework and thesis hours. While these sections are listed as Session D, they follow the add/drop/withdrawal deadlines for Session B.

The maximum credit load allowed by most colleges and schools during Summer Session is 16 credit hours. Graduate students in the School of Education may register for no more than 9 credit hours.

When you add a class to your shopping cart, you'll be prompted to select from the available class options. The deadline to change your grade mode varies by session; see the Session Calendars for details.

Independent study and occasionally regular courses are offered on a variable-credit basis. You must designate the number of credit hours you wish to receive for the course at the time of registration. Visit the CU Boulder catalog for more information about these options.

When a class is full but registration is still open, some departments allow students to join a waitlist to be automatically enrolled in the class if a seat becomes available and the student meets the pre-requisites. Placing your name on a waitlist does not guarantee you'll be enrolled in that class.

If you're automatically enrolled from the waitlist, you'll receive an automated email confirmation. Visit the Office of the Registrar website for more information.

Waitlist deadlines vary by session; see the Session Calendars for details on the last day to add your name to a waitlist and when the waitlist is canceled.
