From time to time classes may be cancelled because of a campus-wide emergency closure, such as inclement weather. Under these circumstances, instructors have the authority to reschedule the missed class at the same time on the next day on which classes are not scheduled (normally Saturday). The agreement of the class is not required in this case.

When the closure occurs during the last week of class in a term, the class can be rescheduled on the first available day between the last day of classes and the start of examinations.

If an instructor cancels a class for other reasons, s/he can reschedule the missed class only with the consent of all students in the class.
