Frequently Asked Questions
How is the weighted average grade calculated?▾
Final Grade = Sum(score × weight) / Sum(weights). Each component is multiplied by its weight before averaging.
What if my weights do not add to 100%?▾
The calculator still computes a proportional grade but will warn you. To get your actual expected grade, ensure weights total exactly 100%.
What percentage is each letter grade?▾
Typically: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = below 60%. This varies by institution.
