It’s a thing of beauty.
I let my employment law students bring a one page, one sided 8 x 11 cheat sheet into their exam. This one is my favourite, though there were others that showed a similar amount of industriousness.
Since there is no name on the sheet, I can’t say how the student did on the exam. But you have to admire the hard work. And the ability (I assume) to read very, very, very small print.
