How do I display the final course grade to students?
Go to Gradebook.
Select the Gradebook tool from the Tool Menu in your site.
Open Grade Release Rules and check "Display final course grade to students".
Check the Display final course grade to students box to show students their final grade in the course as calculated in the gradebook. If you have selected to release the final grade, choose your preferred format for the grade display: Letter Grade, Percentage, and/or Points.
