Summer at CU Boulder is an exceptional time of year! Summer Session classes provide students with a number of flexible options not available the rest of the academic year. However, there are limitations to certain sessions that you need to keep in mind when registering.
Maymester and Augmester
Continuing and readmitted degree-seeking students, new graduate students, and nondegree students may enroll in only one Maymester and/or one Augmester class each summer. You may be enrolled in other sessions as long as the course times don't overlap. High School Concurrent students are not eligible to enroll in Maymester or Augmester sessions.
Classes in Session E and Session F are considered intensives and do not follow a typical session schedule. Classes in Session E take place during the first five weeks of Summer Session, while courses in Session F take place during the second five weeks.
These classes can meet on any days within those windows, so be sure to check the beginning, end and final exam dates before enrolling in a Session E or F class.
Independent Study and Thesis Hours
Any class with a 700- or 800-level section number has controlled enrollment. If you try to register for one of these classes, you will receive an error message. Instead, contact your department administrator or advisor. Once your enrollment dates start, they can enroll you manually.
