How to Calculate Test Grades

A grading calculator converts raw test scores into percentage grades and letter grades based on total questions and missed items.

Grading Calculation Formula

Grade Percentage = [(Total Questions – Wrong Answers) ÷ Total Questions] × 100

Example Calculation

If a student misses 3 questions on a 20-question test:

Percentage = [(20 – 3) ÷ 20] × 100 = 85% (Letter Grade: B)
