The Live calculated scores are calculated on-the-fly by the browser each the Marks book is accessed.
Student summary pages
The Live calculated score is only recorded when changes are made and saved to the Reporting section of the Marks book. Only once this has been done will it show in the Student summary pages.
Discrepancies between the Marks book and the Student summary
If any changes are made to assessment results, weightings etc. which have affected the CalcG and Calc% the Reporting section will need to be resaved. As the system will continue to display the Live calculated score as it was the last time the Reporting data was saved.
