Can I revisit these exercises later if I need a refresher?
Yes! Any exercise on Codecademy can be revisited at any time, so long as you have access to it and have completed the material up to that point. Sometimes we may update courses as well, so you may want to go back through and see the fancy new content!
Any time you want to revisit an exercise, you can reset it using either the reset spinning arrow button, to the right of the Run button, or you can press Get Help in the bottom right and select “I want to restart this exercise”.
