I have Gradebook set up as Weighted Mean aggregation, and Grade categories as Simple Weighted Mean. I aggregate only non-empty grades. All grade items in all categories (Assignments, Classwork, etc) now have max grade of 100.
I'd like to give extra credit to students choosing to complete any one or all of 4 optional assignments, each one adding 1 point to their grade, i.e. they could conceivably add a maximum 4 points to their grade by doing all. Ideally I'd like that additional point (or points) to show up when the optional task is completed, rather than only at the end of the semester.
For example: at week 7, student Marilyn has scores of 80 in every item in all categories, and has also completed 2 extra credit tasks. I would like her total grade to show as 82.
How to do this?
