By default, Blackboard calculates letter grades using the grading scale of 90% -100% for an A, 80% – 89% for a B, etc. If the grades in your course section follow a different grading scale, customizing the Letter Grade Schema will allow you to edit the default schema for your course. This can be especially helpful for entering quarter, midterm and final grades.
To edit the letter grade schema:
- Navigate to the course Grade Center. Select the Manage button and then click Grading Schemas.
- To customize the Letter grade schema, hover over the letter option and click the contextual menu chevron. Click Edit.
- Scroll down to the Schema Mapping section to adjust the grade ranges for each letter grade.
- When you are done, click Submit and the changes to the schema will be saved in your course.
