Frequently asked questions
What if weights do not add up to 100?
It still works. The calculator divides by the actual sum of the weights, so any weights are fine.
Which letter scale is used?
A is 90 and above, B is 80 to 89, C is 70 to 79, D is 60 to 69, and F is below 60.
Can I add more subjects?
Yes. Add as many rows as needed; every row counts toward the same weighted average.
