Now that the semester is over and I'm nice and relaxed (maybe TOO relaxed), I can better appreciate things like this. Here's a priceless piece by Alex Halavais titled How to cheat good.
And for "rookie" instructors, here's a list of ways to cheat on exams. Some are pretty lame, but I've seen others actually used. I'm a bit of a "student of cheating." As I tell my students, "I might have been born at night, but it wasn't last night."
