Gradebook- an example

I will have 3 categories in my course:
             1- activities 30%    -forum discussion 10%
                                  -choice 10%
                                  -wiki 10%
             2- course work 50%   = 25 short quizzes 2% each
             3- final tests 20%   -Part 1 10%
                                  -Part 2 10%

The calculation for this would be: = ([[activities]]*0.3) + ([[coursework]]*0.5) + ([[final tests]]*0.2)
Test weighting has been applied correctly on a student's results in User report!
