 I'm going to demonstrate how to grade using a rubric that has already been set up. So I'll click into a question to begin grading. And I can see that several rubric items have been added here to the comment library. So to use one, I simply drag the comment to the student's paper. So in this case, I might grab the comment, correct roots based on incorrect factors. And I can expand this view here to see the entire comment. Moving on to the next one, I've noticed that it's correctly factored. But there's just one correct root. I can also use some of these negative comments here. And I can continue to add more new comments as I go. And that's how we use a grading group.
