Wrong child logged in

You can try opening a ticket with the Help Center (https://khanacademy.zendesk.com/) and see whether they are able to recover the progress.

Hi Jackie,

I'm sorry to hear you've experienced this issue!

I hate to say this, but unfortunately there's not a way for us to delete or transfer progress between accounts.

For the child that completed the progress on the wrong account, they should be able to quickly gain that progress on their own account by skipping the practice exercises and going straight to the quizzes or the unit test. This is the best way for them to get credit for the skills that they have already learned, without having to completely redo everything.

While there's not a way to remove the progress from your other child's account, they are still able to redo all of the content in the course as many times as they'd like. So, they'll still be able to complete all of the videos, exercises, quizzes, and tests in the course.

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