Gradebook

Aha. One of our local moodle gurus figured it out.

1. We created a "Sum of Grades" parent category containing all assignments.
   
2. Created a "Simple weighted means and grades" category and placed all assignments except the extra credit assignment.

This does leave you with the potential for a >100 aggregation course total. If you know of a way to cap a Sum of Grades category at 100%, it would be helpful.

To the Moodle coders, I would suggest a drop down option on the main page activities section for Extra Credit that would manage this in the background (creating a Sum of Grades parent w/ simple weighted sub and populating only the simple weighted Sub if Sum parent exists already).

Thanks for all your help. It looks like you were prepared to explain exactly this procedure to me after my reply.
