I’m still trying to grasp the scenario.
Are you saying you have instances where you have your category weights to have say summative exams worth 30% of the overall grade and inside that category you place the end of course final examination and you want it to be 20% of the overall grade, meaning every other summative exam summed together must only total 10% and their individual weights summing to 10% also get re-calculated?
Or, in other words, you don’t want point-based assignments in weighted categories, you instead want weighted assignments where the categories are just tags?
I guess I can see that, it is just not how I grade. For instance, I have a HW+Classwork category worth 40% of the gradebook grade, and every single HW I assign is worth 100pt, and every single notebook check is worth 25pt. I do not worry what % of their total grade each notebook check is worth. However, I could see the benefit if I wanted to give a final exam and that if I wanted it to be worth say 20% of their semester grade, that unless I made that it’s own category worth 40% in the Q4 gradebook, that it indeed would take some calculations to figure out the point value if I placed it in my Test category that’s worth 35% of the grade.
I do not see how that effectively works though, as you would have to know the weights for every assignment beforehand to prevent severe gradebook recalculation (e.g., I set each notebook check to be worth 2% of the total grade, but then realize that I assigned more than anticipated and so I have to readjust them so that each is worth only 1% of the total grade).
