This test grade calculator converts one test or assignment's raw input into a percentage, an A–F letter grade, and a fixed 4.0-scale GPA reference. It offers three separate input styles: total questions with wrong answers, total questions with correct answers, or total points with points earned.
It is designed for quick estimates, score checks, and cutoff what-if tests. It is not a school registrar and does not infer an institution's official grading policy.
For multiple assessments, weighted coursework, a required final score, or a school-specific GPA, use a calculator that matches those rules or follow the course policy directly.
wrong-answers: enter total questions and wrong answers.correct-answers: enter total questions and correct answers.points: enter total points and points earned.Question modes require total questions greater than 0; wrong and correct answers must stay between 0 and the total. Points mode requires total points greater than 0; points earned must stay between 0 and the total.
The current page supports wrong-answer mode, correct-answer mode, and points mode.
Yes. The page lets you edit the A, B, C, and D thresholds, while F stays below D.
The current implementation uses a fixed mapping of A=4.0, B=3.0, C=2.0, D=1.0, and F=0.0, with no plus/minus grades or institution-specific rules.
No. The percentage comes from the question counts or points; cutoffs only change the letter-grade and GPA bucket.
No. The page updates live as you change the inputs.
