You can only see the graded assignment if the instructor has included a Feedback file and made it available.
To view the graded assignment (Feedback file) go to the assignment.
The Feedback file will be located in a table at the bottom of the page.
If the instructor has posted a note saying the assignments are available but you don't see your grade, please contact your instructor. In your communication, be sure to include your NetId and which assignment you cannot see in your communication.
