How the Test Grade Calculator Works?
The calculator uses a standard academic grading formula to instantly convert your test results into a percentage score:
Correct Answers = Total Questions − Wrong Answers
Percentage = (Correct Answers ÷ Total Questions) × 100
This ensures accurate, transparent scoring for any single exam or quiz.
Letter Grade & GPA Conversion
Once the percentage is calculated, the tool matches it to a recognized A–F grading scale and converts it into a GPA (4.0 scale). This provides consistent evaluation across different tests and makes results easy to compare.
