Feedback allows you to displays comments to users after they finish a section in a test, based on the grade that they receive. For example, users who receive between 80-100% in a section can receive feedback saying "Good work!", while those who receive a mark between 40-49% can receive feedback saying "You need to re-take this section.".
As the process for adding feedback to a section is the same as for a test, see Adding Feedback to a Test for details.
Note: The Feedback left-hand side menu for a section is displayed when security setting 264: Feedback is enabled.
