Students weren't able to take exams today at the university where I teach. I'm thankful that my class's exams were on Saturday, but I couldn't enter any grades starting around noon. It's working now.
It's going to be a mess for them to reschedule missed exams because the exam matrix is carefully crafted so there won't be any overlap. All upcoming time slots are taken, and students have travel plans to head home so they're not going to want to extend exam week. I don't know what they're going to do and I'm so glad the only hardship for me is that I'm a little behind in my grading.
