Click on a topic, then click 
Submit feedback from the topic's context menu to rate the quality of the content topic from 1 to 5 and leave a comment. You can choose to submit your feedback anonymously or include your name.
You can update your feedback submission by resubmitting feedback to the same topic, but only your newest comments and rating appear to instructors and course administrators. Resubmitted feedback overwrites previously submitted feedback regardless of whether you change your user status from anonymous to your user name (or from your user name to anonymous user).
