Suing for an A
That is exactly what a 51 year old college student did when his political philosophy course was graded on a curve.
So what to do after complaints to the professor failed? Why, file a lawsuit, of course. Amusingly, his reason for filing the suit is because he thought a C would hurt his chances to get into law school. But filing a baseless lawsuit that was thankfully dismissed didn’t seem like a disqualification to him.
Well, if you file suit because you got graded on a curve, then law school, where just about everything is graded on a curve, would not be the place for you.
However, there are lots of lawyers who file rediculous suits in large part because their clients demand it. Of course, when they lose in court they also want to sue their lawyer for malpractice. Unfortunately, lawyers cannot sue their clients for being stupid.
