I attempted to outline the Five Stages of Grade-Grubbing on my own blog but I know that AWC's distinguished readership can suggest improvements.
There's Denial ("but I'm an A student!"), Anger ("You've singlehandedly crushed my dreams of medical school with your totally unfair grading!"), Bargaining, Bargaining, Bargaining...
Come to think of it, maybe it veers away from the Kubler-Ross model when the "Bargaining" stage escalates to the "threats, grievances, and parents going full Boeing Apache on the dean" stage?
