Why generate the guide
Most of making a study guide is copying, and copying is not studying
Sit down to build a guide by hand and the first two hours go on retyping definitions, reformatting bullet points and hunting for the page where a term was introduced. The thinking part, deciding what matters and testing whether you can recall it, gets whatever time is left, which on a Thursday night is usually none. Generating the structure flips the ratio. You start with the concepts, the glossary and the questions already laid out, and spend your time on the only two activities that change your grade: answering questions from memory, and going back to the source when an answer will not come.
