In some use cases, you may want to remove a student from an OSCampus class.
You can clear all data for a specific student by deleting their records in two tables through the phpMyAdmin database management tool or any other database tool of your choice.
The SQL commands to achieve this are:
delete from #__oscampus_users_lessons where users_id = <ID>;
delete from #__oscampus_certificates where users_id = <ID>;
Note: Replace '#_' with the database prefix used on your site. Replace <ID> with the user ID of the student that you can find on the Joomla user manager list.
