Filter work by class
On the To-do page, you'll find work filtered by class,
and see work that’s:
To-do—Work assigned and not yet completed. You’ll
see the class and work titles grouped as missing, no
due date, due today or within the week, or later.
Done—Work you completed and turned in. You’ll see
the status of the work—turned in or done late—and
grades if the work is graded.
