Grading exams and assignments is a crucial part of education, both for teachers and students. Understanding how a score translates into a percentage or letter grade helps measure performance and identify areas for improvement.
How to Use the Test Grade Calculator
- Enter the Total Number of Questions – The total number of problems or points in the test.
- Enter the Number of Correct Answers – The amount you answered correctly.
- Click ‘Calculate’ – The tool will compute your percentage score.
- View Your Letter Grade – Many calculators also assign a letter grade (A, B, C, etc.) based on your percentage.
Test Grade Formula
The formula for calculating a test grade percentage is:
Percentage Score = (Correct Answers ÷ Total Questions) × 100
If letter grades are included, the percentage is compared against a grading scale (which may vary by school or region).
Example Letter Grade Scale (U.S. Standard):
- A = 90–100%
- B = 80–89%
- C = 70–79%
- D = 60–69%
- F = Below 60%
Example Calculations
Example 1 – Standard Test
Total Questions = 50
Correct Answers = 42
Percentage = (42 ÷ 50) × 100 = 84%
Letter Grade = B
Example 2 – Small Quiz
Total Questions = 10
Correct Answers = 9
Percentage = (9 ÷ 10) × 100 = 90%
Letter Grade = A
Example 3 – Essay Scoring
Total Points = 40
Earned Points = 28
Percentage = (28 ÷ 40) × 100 = 70%
Letter Grade = C
