If your instructor makes comments directly on your assignment submission, you can download the annotations and comments.
To do so, locate the downward arrow icon along the upper right side of the submission panel.
When you click the icon, the annotated feedback may download to your computer to be opened, or it may pop open in a PDF reader. The pdf file requires a PDF file reader on your device to view the document.
Once you have the document open, you can save your annotated feedback to a location of your choice.
