This account of a university professor’s battle with cheating was an interesting read. He goes on to tell of how he used the university’s anti-cheating measures, as well as his own tactics, but in the end received the opposite of what he was hoping for: poor professor-evaluations from students resulting in a lower raise in his salary.
