The decision is left to the instructor whether a final examination is held in a course at the close of the semester. Final examinations may not be administered before the scheduled examination period; take-home examinations may not be issued to students before the final day of classes. With the exception of laboratory practica, no test or examination may be administered in the final week of classes. The time of an examination can be changed within the examination period if there is unanimous agreement from students in the class and if an appropriate room can be found by the Registrar. Examination times are posted on the Final Examination Schedule with the exception of courses offered at an irregular time.
