Sometimes There Are Places that You Need to Be at 1pm on a Wednesday

Got the following email last night around 9pm.

I missed my exam today and i was wondering if there is anyway i could make it up. I studied for a long time last night and i new the material. Honestly what happened was i fell asleep in between my 11 o'clock class and yours. Im really sorry and if there is anything i can do i would greatly appreciate it.

I reminded the student that everyone gets to drop their lowest exam grade, so this would be the grade that he'd be dropping. This isn't the only student who missed an exam. There were others, probably some with much more sympathetic reasons.

How much do you want to bet that at least one of the students who missed the exam is going to complain that it's unfair that they have to drop the missed exam while the students who took all the exams get to drop an exam they scored poorly on?
