Is there a way to modify grade book to show Averages, Position etc
And promotions
Am quite new and need some explanations

Hi Daniel,

In School Admin > Markbook Settings you can enable Cumulative Marks, which will show averages in the markbook view. At this time it will only work with Percentage grades, and if your default assessment scale is set to Percentage in System Settings. The markbook averages can be weighted as well, if you Enable Column Weighting.

Hope this helps!
