When you pass your assignment you may want to download the marked copy and keep this for your reference once access to the course ends.
To download a copy of your marked assignment you can either click on the link in the email you received when your tutor marked your assignment, or you can go to the course the assignment relates to and then click on the "Assessment Submission:..." link.
From here, scroll down to the "Feedback" section and then click on the link to the feedback file presented beside the "Feedback files" item in the table as shown below. This will then download a copy of the marked assignment and you can print this and/or save it to your computer.
