What is an Easy Grader?
An Easy Grader (also known as EZ Grader) is a quick grading tool that helps teachers, professors, and educators instantly calculate student scores and grades based on the number of questions and incorrect answers. It's designed to save time during the grading process by automatically computing percentages and letter grades. If you need to convert your marks to percentages, we have a dedicated tool for that as well.
Originally a physical grading wheel or slide chart, the Easy Grader has evolved into a digital calculator that provides instant results. Simply input the total number of questions on a test, quiz, or assignment, and the number of wrong answers - the calculator does the rest.
This tool is especially useful for:
- Teachers: Grade multiple-choice tests, quizzes, and assignments quickly
- Students: Check your own test scores and understand your performance. For college students tracking overall academic performance, try our GPA calculator or CGPA calculator
- Parents: Review and understand your child's test results
- Tutors: Assess student progress on practice tests and worksheets

Frequently Asked Questions
How does an Easy Grader calculate percentages?
The Easy Grader uses this formula: (Correct Answers ÷ Total Questions) × 100 = Score Percentage. For example, if a student gets 18 out of 20 correct, the calculation is (18 ÷ 20) × 100 = 90%.
Can I use this for tests with different point values per question?
The Easy Grader is designed for tests where all questions have equal value. For weighted grading (different points per question), use our Points Calculator in the weighted average grade calculator tool.
What's the difference between 10-point and 7-point grading scales?
A 10-point scale has wider ranges (A = 90-100%), making it easier to earn higher grades. A 7-point scale has narrower ranges (A = 93-100%), making grading more strict. Different schools and states use different scales.
Can I grade partial credit with this calculator?
The Easy Grader works with whole numbers (complete right or wrong answers). For partial credit, you'll need to convert your grading to a percentage first or use a different grading method.
Is this the same as the physical EZ Grader wheel?
Yes! This digital calculator provides the same functionality as the classic physical EZ Grader wheels and slide charts used by teachers, but with the convenience of being accessible online from any device.
How do I round grades?
Most grading systems round percentages to the nearest whole number. For example, 89.5% rounds up to 90% (an A), while 89.4% rounds down to 89% (a B). Check your institution's rounding policy.
Can this calculator handle tests with more than 100 questions?
Yes! Our Easy Grader calculator can handle any number of questions, from small quizzes with 5 questions to comprehensive exams with 200+ questions.
Tips for Using Easy Grader Effectively
1. Double-Check Question Count
Always verify the total number of questions before grading to ensure accurate results.
2. Use Consistent Grading Scales
Stick to the same grading scale throughout a course or semester for fairness and consistency.
3. Consider Rounding Policies
Decide on your rounding approach early and apply it consistently to all student grades.
4. Save Grading Results
Use the save feature to keep records of your grading sessions for future reference.
5. Grade Answer Sheets in Batches
For efficiency, count wrong answers for multiple students first, then use the calculator for all at once.
6. Communicate Scale to Students
Make sure students know which grading scale you're using before they take the test.
