There are two new settings for Tests and Assignments:
Prohibit late submissions – This will prevent students from submitting after the deadline. Any work that has been saved as a draft will be automatically submitted at the due date and the student will receive an email receipt confirming their submission.
Prohibit new attempts after due – This will prevent students from beginning a new attempt after the due date. If a student has already started an attempt before the due date, they will be able to submit after the due date but will be marked as late.
To access the new assessment settings, click on the cog icon in the assignment settings.
