When I was in Jr High, I missed a month of school due to meningitis. I had a month to make the work up, officially. A few teachers waved some portion of the work, and a few did not. It was at their discretion. There was one teacher (Health) in particular who did not follow the rules. While I was out (and believe me, I was out!) she flunked me, even though I had had an A up to the point of my absence. It was one of those 1/2 year courses and I guess I missed the last month or something like that. My mother was LIVID. I mean, she was worrying about me in a life and death sort of way, and this teacher -- who told my mother she did not believe I was that sick -- wanted me to retake Health instead of make up the work. A trip to the principal fixed that... But I still remember the commotion to this day (and that was a looooong time ago). Our current school, many moons later, follows the same general outline, but generally, they don't really expect the work to be made up until 6th grade or so.
