Good luck to you on your paper. When I was doing that course , I was told over and over again - not to over think it. Vianne has certainly provided great ideas.
I have had to read and re-read the info returned to me after having a document returned.
Also I have re-read the initial instructions. Hasn't always helped - but for the most part, re-read has been a help for me. Best of luck to you.
A couple of discussions have helped me:
