B90 was a student in my Evidence course in Fall 2014. He received a grade of "C," one of the lowest in the class. B90 wrote a final exam which suggested that he was not capable of practicing law. His horrible exam notwithstanding, I must admit that—based on my occasional interactions with him—he appears to possess the minimum competency necessary to function as a lawyer. I therefore did not consider it a total travesty when the bar examiners of this state saw fit to grant him a law license.
Please do not hesitate to contact me if you have any questions.
Much though I would love to write a letter like this, I think I'd just decline.
On the original topic:
K5220 has a good suggestion; it's always appropriate to ask what you missed. Though most professors have scars from students challenging grades, this approach is much less confrontational and is more likely to lead to a productive conversation.
