What This Calculator Does

This test grade calculator converts exam or assignment results into a percentage, a letter grade, and a simplified GPA value. It supports three input styles: total questions with wrong answers, total questions with correct answers, or total points with points earned. That makes it useful for both quick teacher-side checks and student-side score verification.

When to Use It

  • You know the total number of questions and the mistakes made.
  • You know the number of correct answers and want the grade fast.
  • You have raw points and want a percentage conversion.
  • You want to compare how different grade cutoffs change the final letter grade.

Inputs Explained

Calculation Mode

The current page offers three modes:

  • correct-answers: calculate from total questions and correct answers
  • points: calculate from points earned and total points

Total Questions

In the two question-count modes, total questions must be greater than 0.
