The Grade areas found on the site are used within an Academic Institution type setting where Tutors can apply manual grading to users Assignment submissions, these areas can be seen across the site in many locations but will not be used for the way in which we use the site for Compliance purposes.
All Activities that are used on the site will generate data based on the type of activity being used, most will output Statuses and Scores from SCORM activity type modules, while Quiz activities themselves will have their own Quiz Grades that are managed independently from the actual site Gradebook.
