Extra credit grade items are not included in the overall course total, but can help raise a student's individual score. You can either create a manual grade item and make it extra credit, or designate an existing activity (Assignment, Quiz, Forum, etc.) as extra credit in the gradebook. Note: If you are going to have multiple extra credit grade items in your course, you might consider creating a cateogry and making the category extra credit instead of making each individual item extra credit.
