To drop or withdraw from a course you must officially modify your registration online within the Academic Calendar dates or by notifying Heather Hicks-Fromdahl, in the Registrar's office, at

Notifying your instructor of your intent to drop or withdraw from a course is not sufficient and may result in you receiving a failing grade and being fully responsible for the tuition.

Courses dropped during the designated drop period will not appear on your transcript. Courses withdrawn during the designated withdraw period will be listed on your transcript as a withdraw with or without a grade, per the Academic Calendar. Students may withdraw from courses at any time before the final exam or submission of final project or before the last class meeting for classes without final exams.



Students may change credit/audit status through the second week of the quarter.


Low enrollment or other scheduling issues may result in course cancellation.


Matriculated students are considered full-time when they register for nine or more credit hours per quarter. Audit units do not count for credit or toward full-time status.
