How To Absorb Textbooks Like A Sponge, by [Matt DiMaio](matt-dimaio.md)

Most people read a textbook the way they read a novel, page one to the last page, straight through. It does not stay in your head. Instead, preview the chapter in several cheap passes before you read it closely.

1. Flip through every page without reading, just to see it. How long is the chapter? Words vs. images? Any graphs? What jumps out?
2. Go to the _end_ and read the quiz questions _first_, so you know what the author thought was important.
3. Go back to the start and read _only the bold print_: titles, subtitles, headings. That is the author's own breakdown.
4. Read the _first and last sentence of every paragraph_ for a section-by-section overview.
5. _Now_ read the chapter once and take notes. One pass is enough.

"You are not reading this for comprehension. You are reading this for exposure... now you're going to have a map of all the dots." Repetition is the mother of learning; the passes prime your "reticular activating system" (buy a blue car and you suddenly see blue cars everywhere).
