Hi there,
Hopefully I'll explain this correctly
We're using moodle 2.8 and a lecturer here has set up multiple categories within the grade book. There is a main category with three sub categories, which were all set up with natural aggregation to add up all results. The lecturers goal was:
Sub Category 1
Has six items, each worth 2% the lowest grading would be dropped. But this could not be done using natural aggregation. I changed this to simple weighted mean of grades which dropped the lowest and produced the correct result in the category total
Sub Category 2
The next category has some quizzes and assignments that calculate up to 30 we changed this to simple weighted mean of grades and the correct result is shown in the Category 2 total
Sub Category 3
The third category is a single submission that is worth 10 percent and the correct total is showing.
However in the main category total I selected natural hoping that it would add up all the sub category totals, but however, it does not. I have tried use a formula and called the totals of category 1: item 1, category 2 :item 2 and category 3: item 3.
The formula is accepted but nothing happens. I have experimented with a few different aggregators but can't get this to work.
I've been looking at this for the past two days with no success, so any help would be greatly appreciated.
Thanks,
Darren
