Instructors can disable comments on Announcements and have that setting applied to every Announcement throughout the entire course. Individual Announcements can be closed for comments.

Instructors can hide the box and whisker plot (grade distribution) graphs to keep students from viewing the summary statistics of the class and figuring out each others' grades. By default, the whisker graph is on.

You can use a join code to enable self-enrollment in your course Settings.

If you want to grade assignments without knowing who submitted them, you can hide student names in SpeedGrader™.

For easier grading, you can sort assignments by student name [alphabetically], the date they submitted the assignment, or by submission status. If your course has sections, you can sort Assignments by section.

You can create a quiz question that requires a numerical answer, such as questions for a math course.
