Finals can run late in the day even on the last day of the exam period. And, you can’t just assume that a test period change can be made-the alternate test period might conflict with another test, etc…individual exams schedules aren’t available until later in the semester. Exam completion times can run all over the place, and even vary by the better part of a week. My son’s midday classes ran on the last days before Thxgiving and Spring breaks, but we were still out of there by noon on Friday. Residence halls closed at 3pm on Saturday for both of those break periods this year.
