Translate a Textbook Chapter Into a Study Guide

You've read the chapter, but a wall of text is no use the night before an exam. This condenses it into a study guide: the three to five core concepts, a one-line definition and example for each, and any formulae or models pulled out where you can find them. The version you'll actually revise from.
