I suspect I would not be any happier to deal with this:
“Is there anything I can do to raise my grade?”
This is worse, because I’ve found out in some cases — from talking to the student — that they REALLY mean, “Will you give me free points out of the goodness of your heart?” Not only would this be academic malpractice on my part, it would be allowing them perhaps to move on to a later class in the sequence without proper preparation or knowledge which doesn’t benefit them OR the person teaching it.
(I have a good heart, but not good in that way, and really, in the long run, it is not good for the person to pass them along unprepared.)
And while I’d be tempted to fall back on good ol’ snark:
I admit I’ve been tempted to say, “Yeah. Build a time machine, go back to the beginning of the semester, and study this go ’round” but that’s not helpful and if someone COULD build a time machine … well, they have no business being stuck in a small regional university; they should be out killing Hitler instead.
I suspect there might be unforeseen consequences in snuffing little Adolf in his crib, and while it’s hard to imagine something worse than World War II, it’s just as hard to be sure that something worse would not happen.
