Body
Follow these steps to remove unwanted columns in your grade center. For example, duplicate copies of the Total or Weighted Total columns that came in from a course import process (please note that you must have one copy of each of those columns in your grade center to enable final gradebook submission).
1. In your course shell go to the Gradebook tab and select grades.
2. Click on the gradebook item to open the drop-down menu.
3. At the bottom of the list, select Delete Column and click OK. This cannot be undone.
*Note: If the Delete Column option is not displayed then that column is still linked with a graded activity within your Blackboard course shell. You will need to delete that activity (e.g. Assignment, Test, Discussion Board) before removing the grade center column.
