"What grade do I have now? I don't know what grade I should try to get on the final exam."
It never occurred to me, when I was a student, to shoot for anything less than an A. I often fell short, especially in science classes, but I never went into a test thinking "I just need to study enough to get a B on this test."
What answer, snarky and non-snarky, would you give to this question? I told the student to work for an A.
