@Gdev apps
I am also really interested in having this feature in the reports for gradebook.
In your example, if assignment 1 was 40% of the category, you could multiply it by the percentage that the category represents of the final grade. You mentioned a weight of 10 but that could be turned into a percentage fairly easily.
Example: If we have 2 categories yours with a weight of 10 and another with a weight of 5, then your category makes up 10/(10+5)=0.667 or 66.7%
In this example, assignment 1 would make up the following percentage of the grade:
0.4*0.667=0.267 or 26.7%?
So even if the weighting isn't displayed, a percentage of course grade display would be useful I think.
