Those faculty reaching more than 100% course total are using Natural aggregation. However they are required to configure their letter grade properly because this is all that matters. This where they need to enter more than 100% grade boundary for a corresponding letter grade but Moodle does not support it.
The letter grade equivalent of the course total of all students that appears in the gradebook of all our courses are automatically integrated/migrated to the Student Information System. We don't care how our faculty configured their course total whether it is more than 100% or not. What we care is the letter grade equivalent of the course total as this will be automatically migrated to our SIS via our integrator system.
