Well, I mean if they hadn't caught on to the guy. They'd have probably been in a study group together, and he's almost certainly unethical enough to cheat.
Good thing he didn't finish his degree and maybe get a doctorate before this came to light, or we'd have someone worthy of the title "Dr. Evil."
ETA: BTW, this has got to be one of the more bizarre college stories in a while, one that really doesn't fit into much of a pattern (hazing, drunken fights, going postal, etc.) Somehow it's spookier.
