What a 40/40 grade means

  • 40 correct and 0 wrong on a 40-question test.
  • Each question is worth 2.5%, so every wrong answer costs 2.5 percentage points.
  • Any score from 36 to 40 out of 40 is an A.
  • A perfect score: nothing above it.
  • It passes a 60% passing score, which needs 24 out of 40.

How to work it out

  1. Divide the score by the total: 40 ÷ 40 = 1.
  2. Multiply by 100: 1 × 100 = 100%.
  3. Find 100% on the grading scale: A is 90% and up, B 80%, C 70% and D 60%, so it is an A.
