About bonus grade items
Bonus grade items are not included in the maximum points for a category or final grade. They are added on top of the calculated grade.
Bonus grade items cannot make users' grades exceed the maximum points specified, unless the Can Exceed option is selected.
Note: Bonus grade items do not display to students with the grade scheme information like other grade items, no matter what display options you set. Because bonus grades are only added to final grades after all other calculations, students can only view the numeric points, and potentially the weight achieved, for a bonus grade, but no other grade scheme information, as the actual weight or points of the bonus grade item may not be consistent with the rest of the grade scheme.
