Quick answer

How is a test grade calculated?

A test grade is the number of correct answers divided by the total number of questions, multiplied by 100. For example, 17 out of 20 is 85%, which is a B.

17 ÷ 20 × 100 = 85% = B

Standard letter grades

A90 to 100%
B80 to 89%
C70 to 79%
D60 to 69%
FBelow 60%
