I have missed my makeup exam this semester. We are given 3 chances at my university to pass a course, 1 regular, a retake and a third exam for those who failed the previous 2 ones. I missed the third exam because of work, and because I almost never able to keep up any schedule.
I wrote an email to my professor to let me retake it, but because I wrote my email at the same time as the exam was, my professor deems it unfair to give me another chance in this.
If I was not a problem student I would agree with his decision, but I spent half a year in a psychiatric ward because I was unable to visit any kind of community, and in this very semester with the help of tranquilizers I almost attended all of my lectures.
