Every semester I have a handful of students (can count them on one hand) who don't show up for a single class or do a single assignment, but they show up for the final exam.

In our system, if a student fails a class, we have to mark the "last day they attended". Since these students showed up for the final exam, I have to say they attended on the day of the final.

Thus, they fail the class, but probably do not lose eligibility for whatever scam they're running.
