How can I submit my homework ?

(a) Navigate to the desired class team, then select Assignments. You can also use your search bar to search for an assignment by keyword.
(b) Your Assigned work will show in order of due date. Select any assignment card to open it and view the assignment’s details. 

(c) If your teacher specified a document for you to turn in or you have other files to attach to this assignment, select +Add work and upload your file.

Note: You can add up to 10 additional resources to an assignment. 500mb is the maximum file size for a resource.

(d) Select the Turn in button to turn in an assignment before its deadline. The button will change depending on the status:

Turn in for group if you’re working on a group assignment. Only one member of the group needs to turn in the assignment.

Turn in again if you’re editing an assignment you’ve already turned in and need to submit work again.

Turn in late if you’re turning in your assignment after the due date, but your instructor has allowed late turn-ins or asked for a revision.

Not turned in if the assignment is past due and your instructor is no longer accepting turn-ins. You cannot turn in work.

Undo turn in if you decide you want to edit your assignment before the due date. You’ll need to turn it in again after you make your edits.
