How to study with these guides

Every lesson works the same way. Follow these steps for each one.

  1. 1

    Watch

    Start each section with its short video (3–6 minutes). It gives you the big picture before the details.

  2. 2

    Read

    Read one section at a time. Study each figure before you move on, and draw the structures yourself on paper. Drawing beats reading.

  3. 3

    Practice

    Cover the right column of each table and say the answers out loud, until you can fill it in from memory. Work through the “how to identify” methods with a pencil.

  4. 4

    Quiz

    At the end of the guide, take the practice quiz. If it has two parts, do Part A (the textbook) first, and score 17 out of 20 or better before you try Part B.

Go deeper Paragraphs and quiz questions marked Go deeper go a little beyond the textbook. Read them to understand why, and check with your teacher before using them on a test.
