Questions about Weighted Grade Calculator
What if my weights total less than 100%?
The calculator reports your average across the entered weight and tells you that the course is incomplete.
Should I enter category averages or individual assignments?
Use whichever level receives the published weight. Do not apply a category weight again to every assignment inside it.
Why is the answer normalized when weights are incomplete?
Normalization describes performance across the work entered. It avoids treating every future assessment as a zero.
