How it works
Percentage = points earned ÷ points possible × 100. The letter grade uses the common US scale (A 90–100, B 80–89, C 70–79, D 60–69, F below 60, with + and −); schools may use different cut-offs. The mark out of 20 is the proportional equivalent used in France, Morocco and many other countries.
