When your teacher releases a grade, the assignment shows Your grade and a View report link. The report is your paper with your teacher's feedback on it.

The grade
At the top of the report is your grade as your teacher chose to show it: a percentage, points out of the total, or a rank, sometimes two of these together. Under it, if your teacher turned it on, each criterion of the rubric with the score you earned and the level you reached ("Proficient", "Developing"). Some reports also show Where you stand: for each criterion, the range most of the class landed in, with a marker for you. It shows the shape of the class, never a rank or a percentile, so you can see that you trail on one criterion and lead on another.
The written feedback
Written feedback is your teacher's summary of the paper. Focus next on lists the two or three things that would most improve your next piece of work, drawn from the criteria where you scored lowest. Notes that are about the paper as a whole rather than one passage appear on the cover page too.
The margin notes
After the cover comes your paper with the feedback in the margins, each note beside the passage it is about. A highlighted passage with a note next to it is a comment; a struck-through passage with new words above the line is a suggested rewrite. Every comment on the report is one your teacher chose to show you. Your teacher may also have chosen a clean copy of your paper with no annotations, or attached the assignment prompt and the full rubric at the end.

Keeping a copy
Download on the assignment saves the report PDF. If you handed in a Word document, a second download gives you your own document back, with your teacher's suggested rewrites as tracked changes and the released comments in Word's review pane, so you can accept or reject each change as you revise.
Your report stays available on the assignment for as long as you are in the class, so you do not need to save it the day it arrives.
If something looks wrong
Grades and comments come from your teacher; the assistant only helps them read. If a grade seems mistaken or a comment refers to something that is not in your paper, tell your teacher the way you normally would. Your teacher can re-open, re-grade and re-release a paper, and a released grade can be taken back and corrected.
