I once had a student who claimed he was never told that he had to take a statistics course.
He was graduating in a couple of months, had invited his family to attend the commencement, and he was asking me to waive his stat course.
Once I reviewed his file, I found out that he had signed up for statistics and dropped it. He did it four times, each time dropping the course during the first week of classes.
Do you think he graduated that May?
