We no longer use quantitative grades but rather mastery scales. I created my own scale with the mastery levels; mastery, developing and exposed.  I choose the level and write a corresponding comment but when I go back in to view the score, it changes to mastery every  time regardless of what I put in.  Is there something I am doing wrong?

Also, I try and add to the comment under the score after I have graded and it won't let me edit the comment. Is there a way around that?

Thank you!
