So what I am using that works is this:
For the course grade aggregation I used "weighted mean of grades."
For the category grade aggregation I used "mean of grades with extra credit."
This is working on all levels and fulfilling what I need.
On a side note, whenever I said grade aggression, I meant grade aggregation. Don't worry, we are not aggressive graders.
If anything we err on the side of grace.
