   Important:

   Extra credit should be set to contribute directly to either a specific grade category, or to the course total grade. An extra credit grade item will contribute either directly to its category (if categorized) or to the course total. If you mark an entire category as extra credit, you must leave the items inside of it marked as "normal", NOT extra credit. Points will not be calculated correctly if both the grade category and the items in it are marked as extra credit.
