I had a group of cheaters, once.
Apparently, the whole lot of them would have benefitted from a class in "How to Cheat Effectively"
They were really bad at it!
Not only did they neglect to make even the most cosmetic of changes so that the files they all handed in would at least LOOK different, and they didn't change the file name to at least make it a ~little~ more challenging for me to find them (how insulting!), they forgot the #1 rule of cheating.
Find someone smart to cheat off of!
The database they handed in - each and every last one of them - wouldn't have passed even if I hadn't divided the mark by 7!
