Wow, you have created your own NFT collection from scratch. What a superstar! You have learned tonnes of new concepts and code - that is really impressive! And now you're almost ready to test yourself a little bit more.
885+
886+
But first, we want you to go and 'touch some grass'. So why don't you scroll to the top and set the pomodoro timer, and when you come back after your well earned rest, take the quiz. Breathe and enjoy.

Congratulations on your results. You're now a supreme open-sourcerer! See you in the next lesson, where you will be adding to your knowledge of creating ERC721s, by creating *tiered NFTs*. See you there....
