I wanted to make sure I correctly understood excluding empty grades, in order to avoid unexpected results. I understand the general principle just fine and have used the feature regularly. Here's what I'm not completely sure of:
Let's say I have the overall course parent category, then I have two levels of subcategories below it.
If all three are checked to exclude empty grades, I expect all empty grades in the course to be excluded.
If the parent, overall, course is checked to exclude empty grades, but subcategories are unchecked (meaning empty grades are included), what is the effect?
If the opposite is true (parent category is unchecked, but subcategories are checked), what is the effect?
