Can Students Repeat Assignments?
If a student doesn't complete an assignment before the due date/time, meaning their assignment is labeled as "In Progress (Late)" or "Unstarted (Late)", they can still complete it after the due date to receive a new label of "Completed (Late)".
Once they've truly completed the assignment, they can go back and repeat it, but doing so will not affect the completion label on the assignment. (It will still be marked as "Late" in some form.) If the assignment was a vocabulary quiz, they can click on the assignment in their Classrooms dashboard to go to the list page, where they can click a "Get Started" button to take additional quizzes on that list. If it was a grammar lesson, they can click the link in the Classrooms dashboard to run through the lesson again.
