Letter / Level reporting is now available for GradeBook! You will have to create a new GradeBook to see this new feature. You can now display percent, letter/level or both on reports.
See our user guide here for instructions:
I did but now I get something like A+% , in other words, the letter grade and the sing of percent, but not both
What would be most useful is the possibility to show both letter and percentage directly on the Grade Book sheet, next to or instead of the colour coded performance, or next to the percentage column
On the settings sheet please change GradeBook Display Grades as to Letter. I believe it is cell B23. Once this is set to letter you should see both
I followed the instruction, selected "Both" but only percentages show up in the course report.
