How is this calculated?

Each question is worth 100 ÷ 51, which is about 2.0%. To score a test, divide the number correct by 51 and multiply by 100.

A student who misses 6 gets 45 correct, so the score is 45 ÷ 51 × 100 = 88.2%, 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.
