I have never skipped a test or exam (or even just a day of school) for illness. However, if I were too sick to go to school and write a test one day, I would need a doctor's note in order not to get a 0 on the test. Apparently, university policy is that the doctor's note must be written for the day of the test. This is a concern for me because if I were ever too sick to go to school to write a test, wouldn't I be too sick to go to the doctor's and get a note? I would get an automatic 0 on the test...
