As longtime readers know, I'm no fan of the "D" grade. Basically, I don't understand it. (For the longer version of my anti-D diatribe, see here.) It's passing, sort of, but it won't get taken in transfer unless it's safely hidden among other, higher grades. It gives credit, but in some sequences, it doesn't let you move forward. As grades go, it's particularly ambiguous. Last week, I heard a new twist on the evil of D's.
