Student A: "Professor, what do you mean, I can't pass?"
Me: "No."
Student A: "I know I have a 32% exam average to date, but I really do know the material!"
Me: "Ummm...no, you don't".
Student A: "But what if I do really well on the final?"
Me: "You would need to get a minimum of 173% on the final to pass. And I'm afraid I do not offer extra credit. You. Can't. Pass."
Student A: "But...but, I'll do homework from now on, honest."
Me: "It's over, move on".
Student B: "Professor, what do you mean, I can't pass?"
Me: *sigh*
