It’s time for some practice with structures. You can find the challenge in the “06 - Challenge - Structures” page of the playground you’ve been using, or you can download a new one from the resources for this video. Open it up, and try solving the challenge questions on your own, then keep watching to compare your work to mine. Good luck!
