I'd like to add to this. The option to reset the progress indications for videos and the skills markers, per Unit.
For example, I'm going back through and completely doing the Pre-Algebra Unit: Proportional Relationships unit over again. As such, it would be helpful if I could remove or reset the previous progress and completion/skills indicators from this unit, in order to keep track of my current progress of viewing the video lessons and accomplishing the skills test, as I progress through the unit again.

Hi there,

Unfortunately, there's no way to delete progress within a specific course. This is intentional in order to prevent accidental progress loss.

If you'd like to restart a course, I suggest creating a new account or a child account to start fresh.

Additionally, you're always able to go back and re-do any of the content that you've already completed on your account, you just won't be able to mark it as not completed or reset your mastery progress.

I hope this helps! Please let me know if you have any additional questions!

agree with the need for a reset button. i completed the intro to html/css course a few years ago. i want to retake it as i have a class this fall that deals with it. i feel this can be solved by either requiring a password to reset, requiring teacher/coach permission (if available), or create a new 'session' for that course. the new session would reset the course progress while having the option to go back to the old session (to prevent any permanent loss with resetting)
