How do I modify the way Canvas calculates letter grades? (Instructors)

All Butler courses are set up with a course grading scheme, the Butler A-F Grading Scheme, enabled by default so that courses display a running course letter grade to students. To change the grading scheme:

1. In your Course Navigation, click Settings.
2. Click the Course Details tab.
3. Under the Enable Grading Scheme checkbox, click View Grading Scheme.
4. Canvas will show the default grading scale. 
   1. To select a different scale (one that has already been created), click Select Another Scheme in the top right corner of the box. 
   2. To edit the grading scale, click Manage Grading Schemes in the bottom right corner of the box.
5. Click the Done button.
6. Click Update Course Details.
