In grad school, a couple of times I proctored exams for my major professor. Every time I caught students cheating (copying off of note sheets or old exams from other students), collected the "cheat sheets" and explained the situation to my major professor. Not once were those pursued and I think all the students passed the classes. Pretty frustrating.
