You can extend the deadline for an assignment by modifying the due date for the assignment. Modifying the due date of the assignment will allow every student to use the new due date. If you want to extended the deadline for specific students only, then use the Extend a due date feature. When you delete an assignment you will also delete all student documents that were submitted for that assignment. Students may notice that their receipts and history for the deleted assignment were also removed.
Deletion is permanent, so please be careful when deleting assignments.
After selecting the delete option, you will be asked to select the assignment to delete. The assignment information will be displayed on the next page. Next, select the assignment for which you want to extend the deadline. Below the assignment list is the list of all the students in your course. Once you've selected the assignment and students, then select the new due date.
