It is the final day to use the enrolment system to drop a course. If you do not want a final grade in a course, then you must use the enrolment system to drop the course on or before the withdrawal deadline date. You are responsible for the accuracy of your enrolment record, and for the accuracy of any adjustments you make to your record. You should review your courses after every transaction (add, drop, or section change). It is important that you do not remain enrolled beyond the withdrawal deadline in any course for which you are not prepared to receive a final grade.
