Another comic on the topic of gaming the educational system, a follow up to the previous Calvin and Hobbes and the original topic of studying for exams. This time from Wondermark (image links to a higher resolution original).
I had a student devise an elaborate scheme where he reduced vast swaths of the textbook into a shorthand notation that he printed onto his hands with ultraviolet ink. Then he put a tiny LED blacklight into the bridge of his glasses. Much harder than simply studying, of course.
Actually a brilliant scheme, if this was to work.
