# Grading a roll.

This feature allows a roll to be graded on a linear scale. The percentage of the total number of hours in a course a student is present for is added as a grade in the gradebook. Tardies are included in this calculation as well, and are graded based on the "number of tardies per absence" configuration for the module.

This feature does not work very well when automatic attendance is turned on because there is currently no way for a student to be partially present in a course on a given day. A student is 100% present or 100% absent in terms of automatic attendance logging.
