Daytime classes meeting at times other than those scheduled above will make use of the examination period scheduled for classes covering the largest portion of the usual class meeting time. Final examinations are given at the option of the instructor.  If given, they must be administered at the time scheduled above.  Last unit exams also must be given at this time unless the examination period is used for: a) comprehensive final, b) the due date for final work in the course, or c) some comparable concluding assignment or examination.
