What I got from his post wasn't that he deserved a better grade, but more willingness by the professor to field his questions. If other students felt this way, I really can't trust the author's claim that his low evaluation score was solely due to the fault of his students. Seems pretty unfair...
The cheating, although not excusable, could very well be partially blamed on the professor.
