How about I do nothing except take my exam as normal?

Oh no, that would be a dick thing to do. Actively subverting them... by taking an exam in a class they also happen to be enrolled in... Pure entitlement culture.

If they ask, they won't fuck themselves over. If they don't ask, they will fuck themselves over. They are responsible for what happens to them. As long as they do not ask me for my input, I have no responsibility for their actions.
