Built with teachers and students in mind, this tool handles everything from simple quizzes to complex exams with extra credit and custom grading scales.

Key Features That Set Us Apart

Instant Grade Calculations: Enter the total number of questions and wrong answers to instantly see your percentage grade, letter grade, and correct answers. Our test calculator processes results in real-time as you type, making grading faster than ever.

Flexible Grading Options: Unlike basic grading calculators, we support half-point (0.5) and quarter-point (0.25) scoring for detailed assessment. This is perfect for tests where partial credit matters, such as math exams or essay questions with multiple parts.

Custom Grading Scale Table: Adjust the letter grading scale to match your institution’s grading policy. Set minimum thresholds for A+, A, A-, B+, and all other grades. Whether you follow a High School grading system or College standards, customize the grading scale table to fit your needs.

Visual Grade Distribution: Our unique visual grade bar shows exactly where your score falls on the spectrum from F to A+. This data analysis feature helps students understand their performance at a glance and teachers identify class trends.

Plus/Minus Letter Grading System: Toggle between simple letter grades (A, B, C, D, F) and detailed plus/minus grades (A+, A, A-) depending on your grading policy. This flexibility ensures corresponding grades match your institution’s requirements.

Advanced Features for Precision Grading

Partial Credit Support

Real-world tests often award partial credit. Enable half-point or quarter-point scoring to grade with precision. This feature is essential for:

• Multi-part math problems where each step earns points
• Essay questions with subsections
• Science labs with multiple data analysis components
• Assignment scores that use the point system

Complete Grade Breakdown Table

View a comprehensive breakdown showing every possible score. The grade table displays correct answers, wrong answers, percentage grades, and corresponding letter grades for each scenario. This grading scale table helps teachers create answer keys and students understand exactly what score they need for their target grade.

Extra Credit and Bonus Points

Reward students who go above and beyond. Our calculator seamlessly incorporates extra credit into the final grade calculation. Simply enter bonus points, and the tool recalculates the percentage based on total points possible, including the extra credit.

Understanding Your Test Results

Percentage Grade Explained

Your percentage score represents earned points divided by total points, then multiplied by 100. For example, if you answer 18 out of 20 questions correctly, that’s 18/20 = 90%. This is your percentage grade before any extra credit.

Letter Grading System

The default letter grading scale follows standard academic conventions:

• A+ (97-100%): Excellent performance
• A (93-96.99%): Outstanding work
• A- (90-92.99%): Very good achievement
• B+ (87-89.99%): Above average grade
• B (83-86.99%): Good performance
• B- (80-82.99%): Satisfactory work
• C+ (77-79.99%): Average performance
• C (73-76.99%): Acceptable grade
• C- (70-72.99%): Below average
• D (60-69.99%): Passing grade (minimum)
• F (0-59.99%): Failing grade

Customize these thresholds in the settings to match your specific grading policy.

Earned Points vs. Total Points

Understanding the relationship between earned points and total points is crucial. If a test has 25 total questions and you answer 20 correctly, you’ve earned 20 points out of 25 total points. Add 3 bonus points, and your earned points become 23 out of 28 total points possible,that’s 82.14%.
