A Test Grade Calculator (also known as a Test Calculator) is a simple yet powerful tool that helps students quickly determine their test results.

This tool is perfect for exams, quizzes, mock tests, and practice assessments where you want instant feedback.

What Is a Test Calculator?

A Test Calculator is designed to calculate your test score based on how many questions you answered correctly. Instead of manually counting and calculating percentages, the tool does everything automatically and accurately.

It works for:

• Multiple-choice tests
• Online quizzes
• School exams
• Practice tests and mock exams

How the Test Grade Calculator Works

Using the Test Calculator is straightforward and requires only a few inputs.

Step 1: Select a Grade Scale

• Default scale: A–F
• Can be customized to match your school’s grading system

Step 2: Enter Total Number of Questions

Example:

• Total questions = 50

Step 3: Enter Number of Wrong Answers

Example:

• Wrong answers = 7

Calculations Used by the Test Calculator

Once you enter the values, the calculator performs the following steps:

1️⃣ Correct Answers

Correct Answers = Total Questions − Wrong Answers

Example:

50 − 7 = 43 correct answers

2️⃣ Percentage Score

Percentage = (Correct ÷ Total) × 100

Example:

(43 ÷ 50) × 100 = 86%

3️⃣ Letter Grade Assignment

Your percentage score is matched to the selected grading scale.

Example (A–F scale):

• 90–100% → A
• 80–89% → B
• 70–79% → C
• 60–69% → D
• Below 60% → F

= 86% = B
