How to restart a course
If you want to restart a course from the beginning, you can delete your progress. Here's how:
Open the course you want to restart.
Scroll down on the right-side panel and click the cog wheel to open the course settings:
In the Course Settings pop-up, click 'Delete.' This will erase all your progress, allowing you to start the course from the beginning.
This action cannot be undone. A confirmation window will appear, so please proceed with caution!
