Suck

A C+ is truly a ridiculous grade. It's like being given a big pile of dog poop with a little gold star on top. Really, it's almost worse than just getting the C. At least then there's no hope that you could have come out with a B-.

And by the time you get to the C/D range, why even bother with the +/- modifiers? Why waste your time separating the hopelessly stupid from the mere idiots?
