Student Work for a Lesson / Module
that is subsequently Unpublished will still be retained by Lt - however it will not be accessible
by either Administrators or Students until
the Lesson or Module is Published again.
If you want to allow Students to still have access to their work, you should switch the Grading Mode to PDF Grading (Course of Interest | Settings | Grading Workflow) and prompt the Students to log in and download any PDFs they wish to retain, prior to Unpublishing.
