Student creates an incredibly detailed "cheat sheet" for final exam

A Reddit user posts: "We can bring one A4-size note for finals so I copied the whole semester of class material into it."

Of course, reviewing and copying down key points is a good way to… learn the material.

That said, I think the creator should make a line of these cheat sheets for various classes and offer them for sale in the student bookstore. Suitable for framing!
