Frequently asked questions
How is the grade calculated?
Percentage = correct answers ÷ total questions × 100. It is then converted to the chosen scale: out of 10, 20 or 100. Questions with different weights are not part of this calculation.
How does the A to F grade work?
It is the most common scale in the United States: A from 90% to 100%, B from 80% to 89%, C from 70% to 79%, D from 60% to 69% and F below 60%. Schools may use different cut-offs, with + and −.
