In the event that you have added a course product key to yourself or any other student by accident, you have an opportunity to release the course product key**.
** Course product keys can be released as long as there are no chapter progress and an exam has not been attempted.
To release a course product key, you must have the course administration application configured. Inside the course administration app, you can find the student you would like to revoke access to in the "Student Progress" menu. Click “More” to open the student info panel with “RELEASE PRODUCT KEY” button if permissible by the application.
