In autumn, winter, and spring, the first three weeks of the quarter mark the period to add/drop courses, language reading examinations, and make other enrollment changes. In summer quarter, the add/drop schedule varies based on the length of the course.

Courses dropped after the add/drop period has ended are noted on the student transcript with a grade of "W". A late change fee ($50 for the current quarter and $150 for a prior quarter) is assessed for any enrollment change processed after the add/drop period has ended. There is no refund of the language exam fee ($70) for exams dropped after the third week of the quarter. Late add/drop requests should be made through the Dean of Students office.

The University maintains a strict tuition refund schedule published on the website of the Office of the Bursar.
