Our interactive contour quizzes aim to help improve your understanding of contours.

New May 2020 - This won't work on all computers and browsers but if it does it's more modern than the older quizzes and works on touchscreens (will use a lot of mobile data ~30MB).

There's a tutorial to help get started and if you find it too difficult, you can increase the time limits in the Settings page and watch out for hints at the bottom of the page when you get one wrong.

 As your skills improve, you can alter the time limit on the exercises to make them more challenging.
