How it works
The percentage is calculated by dividing earned points by possible points. The letter label is a common 90/80/70/60 scale and may differ from your school policy.
Standard formula
points earned ÷ points possible × 100Worked example
86 points out of 100 equals 86%, which is a B on the common scale used here.
