When you finish an exercise, whether it's correct or not, you have the opportunity to do it again. The goal is to allow students and teachers to do an exercise until it is correct, or to improve the code they have created, promoting the spirit of trial and error.

In the case of the exercises you find within each of the lessons, you can complete them again whenever you want by simply clicking on the Retry button. In this way, your exercise will be restarted and you will lose the solution you programmed earlier.

In the case of quizzes, you can press the Retry button to correct your mistake or repeat it even if the answer you selected is already correct.

We also remind you that, in the case of quizzes, you can only find out the correct answer when you get it right (the platform won't reveal it beforehand).
