On your Gradebook Dashboard, click “manage gradebook” next to the first period.
Click “Final Marks.”
Change the low and high end of each mark you want to use.
If you round up, you want the A- to be 89.5% - 93% and the B- to be 79.5% - 83% etc.
If you don’t use + and - marks, make the A+ 0.00 - 0.00, the A 90.0 - 100.0 and the A- 0.00 - 0.00, etc.
When you click “save changes,” marks you don’t want to use will no longer be listed in your grading scale.
You will have to change your grading scale (“Final Marks”) for each individual gradebook.
