Test Grade Calculator

Calculating exam grades for multiple students manually can take time and effort. Our free test grade calculator makes this process quick by instantly determining your score using the number of correct and incorrect responses. It also assists in automatic grade scaling and performance evaluation.

What Is a Test Score?

"A test score represents the measured performance of a student or participant in an assessment."

With the help of an online calculator, you can compute this score accurately within seconds without manual calculations.

How to Calculate Test Scores

The standard formula used to determine a test score percentage is:

Percentage Score = Correct Answers / Total Questions

Because the total number of questions includes both correct and incorrect answers:

Correct + Wrong = Total

The formula may also be expressed as:

Percentage Score = (Total − Wrong) / Total

Letter Grades Chart

Educational institutions commonly convert percentages into letter grades using grading bands such as the following:

Letter Grade	Percentile
A+	97–100
A	93–96
A-	90–92
B+	87–89
B	83–86
B-	80–82
C+	77–79
C	73–76
C-	70–72
D+	67–69
D	63–66
D-	60–62
F	Below 60

Example

Statement: Reshaeel attempted a test containing 110 questions and answered 89 correctly. Determine the percentage score and corresponding letter grade.

Solution:

Total questions = 110
Incorrect answers = 110 − 89 = 21
Percentage Score = 89 / 110 ≈ 0.809 ≈ 80%
Letter Grade = B-
