Using 'Weighted mean of grades'

The first feature of the new grade book that some may want to be able to master is the ability to 'clump' assignments into categories and then have each category be assigned a different weight in the overall final grade. (Note - The non-technical term 'clump' is being used to avoid the term aggregate in the hopes of preventing confusion given the terminology used in the new grade book)

Example (how some courses are evaluated using categories)

Attendance & Participation 40%, Quizzes 20%, Tests (Mid-term & Final) 20%, Final Projects 20%,

For this short doc two categories were utilized (Reading and Writing) and 4 Assignments (offline activity).

So after creating the 4 assignments this is what it should look like (roughly).
