The Final Grades page lists the calculated final grade for each student in your gradebook. Final grades might be inaccurate if:
You did not select the Automatically keep final grades updated option when you configured your Grades settings.
There are grade items that you still need to enter grades for.
You selected Automatically release final grades but you didn’t change your selection from Drop ungraded items to Treat ungraded items as 0 at the end of the course.
You are using formula grade items in a points-based grading system. Formula grade items do not contribute to the final grade in a points-based or weighted-based gradebook.
