If your instructor creates a cloud assignment with a Google Drive file, you can edit the document directly and submit your changes as your assignment submission.
When you open the assignment, Google Drive will create a copy of the file as your submission. You can make changes per the assignment instructions, and submit the assignment directly from the assignment page. The copied document is also added to your Google Drive folder for the course.
Cloud assignments are treated the same way as any other type of assignment submission. When you submit your assignment, your instructor will view the assignment exactly as it is when you click the Submit button. Even though cloud assignments can still be modified in the assignment page, any changes you make to the assignment after the submission cannot be viewed by your instructor unless you submit the assignment again as a resubmission.
Note: If enabled in your account, Canvas plays a celebration animation when you submit an assignment on time. However, if you prefer, you can disable this feature option in your user settings.
Make edits directly to the document as necessary to complete the assignment . Google will periodically save your changes .
When you are ready to submit the assignment, verify that all edits have been saved, then click the Submit button.
Confirm your assignment was submitted.
If you need to make changes, you can edit the assignment again and submit the assignment as a re-submission.
