Important Information to consider when adding a course:

 

Adding Courses and Payment Deadlines:

  • If you have already paid for your courses, and decide to add an additional course before the add deadline, the tuition and fees for your new course are due immediately.
  • If you add courses after the cancellation date has passed, you are responsible for all tuition and fees associated with your enrollment.  You may be canceled for non-payment if payment is not received immediately. If you fail to drop your courses before the refund deadline, you are also responsible for tuition and fees. 
  • If a student drops a course and adds a new course after the refund deadline, the student will be responsible for the fees for both courses. Tuition and campus-based fees will not reverse for a course dropped after the refund deadline. 
  • If you wish to add a class after the Deadline to Add a Class, you will need to submit a Late Add Request via the Enrollment Authorization System (EASy).  Late adds are not guaranteed. If you are approved, payment is due right away. For more information, visit the How to Add a Class page on TritonLink.

Unit Enrollment Limits:

  • UC San Diego Students: You may enroll in up to 12 units for Session 1 and Session 2, and 15 units for Session 3. To enroll in more than 12 units, you will need to submit a Unit Limit Exception through the Enrollment Authorization System (EASy) via TritonLink starting the first day of classes. Please note: Unit Limit Exceptions are rarely approved.
  • Visiting Students: You may enroll in a maximum of 15 units per session. To enroll in more than 15 units, you will need to submit a Unit Limit Exception through the Enrollment Authorization System (EASy) via TritonLink starting the first day of classes. Please note: Unit Limit Exceptions are rarely approved.
  • High School Students: Are encouraged to enroll in up to 4 units per session; 4 units per session is considered full-time and is the recommended course load. However, you are allowed to enroll in up to 8 units per session.
