Help Us Test These Lessons

How a review works

1. 1Do the lesson from top to bottom, including the practice problems. Use the Hint and Show next step buttons whenever you want. Nobody is grading you.
2. 2Open the review form for that lesson and fill in the three parts: how it read, whether it taught what it promised, and your verdict. Honest beats polite. "This part was boring" is useful. "It was fine" is not.
3. 3Download your review as a PDF and send it to the person who asked you to review. Nothing you type is saved on the website or sent anywhere by itself.

If you would rather write by hand, each form has a button for a blank copy you can print.

What makes a great review

The best reviewers point to a specific spot: "the socks and shoes picture made the order click," or "I did not get why the 1 appears in problem 5." In Part 2 of each form you solve a few problems without looking back at the lesson. If you get stuck, that is not a mark against you. It tells us exactly where the lesson has a gap, so write down where you got stuck.
