Examples
Weighted categories
Homework 40% (95%), tests 60% (82%).
0.4 × 95 + 0.6 × 82 = 87.2%.
Three categories
Homework 30% (92%), quizzes 20% (80%), exams 50% (85%).
0.3 × 92 + 0.2 × 80 + 0.5 × 85 = 86.6%.
Weights warning
If your weights do not sum to 100%, the calculator will warn you.
Adjust weights until they add up to 100%.
How it works

FAQ
Can I use this for unweighted grades?
Yes. Add one category at 100% (or keep equal weights across all categories).
Do weights have to add up to 100?
No, but the calculator assumes they do. If they do not, it will show a warning.
Is this the same as a GPA calculator?
No. GPA calculators use credit hours and grade points; this is for a single class average.
