You can reset individual course progress if you've begun or finished a course and want to erase all of your code from the completed exercises.
To Reset Course Progress:
• Make your way to the course you'd like to reset.
• Select any lesson by clicking View Chapter Details.
• Select Course Outline from the drop-down menu.
• Choose Reset Course Progress from the drop-down menu.
This action cannot be reversed, however the XP earned on your profile will be preserved.
If you want to retake a course, you can Reset Course Progress, which erases all of your previous progress in that course as well as any saved codes.
The XP earned from a previously finished course will not be deducted from your overall XP.
