You may have circumstances that you believe justify waiving the drop deadline. You should be aware, however, that you are expected to assess your academic progress in each of your courses, and the impact that your personal, family, medical, financial, or employment circumstances are having on each course, before the withdrawal deadline. If you could have assessed the need to drop a course before the withdrawal deadline, then you must explain why you did not.
Visit Petitions and Grade Reappraisals for further information on deadlines.
