How is a test grade calculated as a percentage?

Grade Percentage = (Points Earned / Total Points Possible) × 100. For example, getting 45 questions right out of 50 is (45 / 50) × 100 = 90% (Grade A).

What is the standard letter grade scale?

The typical US grading scale is: 97–100% (A+), 93–96% (A), 90–92% (A−), 87–89% (B+), 83–86% (B), 80–82% (B−), 77–79% (C+), 73–76% (C), 70–72% (C−), 60–69% (D), and below 60% (F).
