How is this calculated?
Each question is worth 100 ÷ 90, which is about 1.1%. To score a test, divide the number correct by 90 and multiply by 100.
A student who misses 10 gets 80 correct, so the score is 80 ÷ 90 × 100 = 88.9%, which is a B.
Letter grades use this scale: A 90–100, B 80–89.9, C 70–79.9, D 60–69.9, F below 60.
Gave partial credit? See the half-point chart
Half-point grading lets you take off half a point for an answer that's partly right. A cardboard EZ Grader can't do it, because it only counts whole numbers wrong. Easy Grade Premium can, at any test size.
