Home > Enable Completion Tracking in Your Course > Completion Tracking (tags next to assignments) > Activity Completion: Student Must Submit a File to an Assignment
These steps require that completion tracking be enabled in your course.
A common activity in Moodle is to have students submit a file or text to an assignment. You can set up Activity Completion to mark a forum as complete if the student makes a submission.
NOTE: You can’t automatically check to ensure your student’s uploaded the CORRECT file, but you can require that at least something is submitted before the item is marked as complete.
We strongly advice that you not to use this type of Activity Completion to Restrict Access to an answer key since students can submit an empty file to gain access.
