2. Then click the 3 dots in the upper right of the assignment tile.
3. Click the calendar icon to the right of the "Due date" field.
4. Click to select a date. Then click "Done".
5. Next to "When past due", adjust the dropdown to choose whether you'd like the assignment to remain available to students after the due date or if you'd like access restricted.
Restricting access will make it so students cannot rewatch content within an assignment after the due date, but will keep them from continuing test attempts (should they have any attempts left available per the class setting).
