This scenario describes the actions an instructor can perform on tests for which grading has not been completed on a student by student basis.
The professor can add notes to a student response by clicking in the notes textbox.
The professor can also change the number of points a student receives for a particular question.
Once the professor is done editing the questions in the test, he can save the changes by clicking the Save Changes button at the bottom of the page. If undesired changes were made, instead the professor clicks Cancel Changes and none of the changes write to the database.
