Switch the main course gradebook aggregation.

The current gradebook is out of 480. We will switch the aggregation to a simple weighted mean of grades so it is out of 100.

Current gradebook total above 100.

After switching the aggregation it defaults the total points to 100 (it does give the option to alter this value to whatever we want using this aggregation type) :

Simple Weighted Mean aggregation applied to the course total instead.

Points will scale based on the total in each category to make the course is worth 100 instead of 480.
