FAQ

How is weighted average calculated?

Sum of (grade × weight) ÷ sum of weights. Example: (90×0.4) + (85×0.3) + (80×0.3) = 85.5.

Why do weights matter?

Higher-weighted categories (like finals) impact your grade more. A 50% exam hurts more than a 5% quiz.

Do weights always sum to 100%?

Yes, they should. If your syllabus weights don't sum to 100%, proportionally adjust them.
