Great letter
When there was a walk out planned at my high school back in the sixties one of my teachers said simply “I am giving an exam on that day. Your JOB is to be here and take it. If you aren’t here you will get a zero. This exam will weigh heavily on your final grade”
My class stayed in that day....except two people who flunked that class because of that test
Yes, I would have given a test that day. No make up. 90% of the six weeks grade.
