Grading Scale Options – Standard, Plus/Minus, and Pass/Fail
The class grader supports three USA grading scales used in K–12 and higher education. Select your scale before grading — it applies to every student in the batch automatically.
- Standard (10-point): A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%
- Plus/Minus: A+ = 97–100%, A = 93–96%, A− = 90–92%, down to D− and F
- Pass/Fail: 60% and above = Pass, below 60% = Fail

Gradebook Calculator – Grade Your Entire Class at Once
This entire class grading tool is designed for batch grading. Enter your total questions once, paste your full class list, and get every student’s percentage, letter grade, and GPA in a single click. For grading one paper at a time, use the teacher grading app instead.
Grades Computation for an Entire Class – How the Math Works?
The class grader uses a straightforward formula for every student: (Total Questions − Wrong Answers) ÷ Total Questions × 100 = Score Percentage. That percentage is then matched to your selected grading scale to assign a letter grade and GPA.
For a 25-question test with Standard scale: missing 3 = 88% (B), missing 5 = 80% (B), missing 8 = 68% (D). The class grade calculator runs this computation for every student in your list simultaneously. The same math a teacher would do manually, completed for 30 students in under one second.
This is what grades computation means in practice: bulk score calculation that eliminates the repetitive arithmetic of grading by hand.
Class Grade Calculator for Fast Grades Computation
Instead of calculating each score manually, the tool automatically converts wrong answers into:
- percentage scores
- letter grades
- grading scale results
This helps teachers calculate class grades quickly while reducing grading errors.

FAQs: Bulk Class Grading Calculator
What is a class grader?
A class grader is a bulk grading calculator that computes scores, letter grades, and GPA for your entire class at once. You enter the total questions on the test once, paste your full student list, and every student’s percentage, letter grade, and pass/fail result is generated in a single click. It is designed exclusively for batch grading a whole class roster, not for grading one student at a time.
How is the Class Grader different from the Teacher Grader or Easy Grader?
These three tools serve completely different purposes. The easy grading calculator is designed for students and individuals checking a single score quickly. The teacher grading calculator grades one paper at a time and useful for quick individual lookups during class. The Class Grader processes your entire class roster simultaneously. It is the right tool when you have a stack of 20 to 100 papers and need every grade computed in one operation. If you are grading more than one student at a time, this is the tool to use.
Who should use the Class Grader?
This entire class grading calculator is built for classroom teachers who need to grade a full set of tests or quizzes for an entire class. It works best for K–12 teachers, college instructors, tutoring centers, and department heads who need batch grading results and a grade distribution report. It is not designed for students checking individual scores. The online grader for single test handles that use case.
What types of assessments can I grade with this tool?
The Class Grader works for any objective assessment scored by correct and wrong answers, multiple-choice tests, true/false quizzes, spelling tests, math drills, vocabulary tests, and short answer worksheets. It is not designed for essays, creative writing, or rubric based assignments, as those require teacher judgment rather than a fixed formula.
How do I use the Class Grader to grade my entire class?
Three steps. First, enter the total number of questions on the test. Second, paste your student list in the format Name: Wrong Answers — one student per line (example: Alice: 4). Third, click Grade Whole Class. Every student’s correct answers, percentage, letter grade, GPA, and pass/fail status appear instantly. The class average and pass rate show above the results table automatically.
How do I calculate class grades if I only have the number of wrong answers?
That is exactly what this tool is built for. Enter each student’s wrong answer count (you do not need to calculate correct answers first). The class grader subtracts wrong answers from total questions automatically for every student, then computes the percentage and letter grade. You can enter just numbers (one per line) without names if you prefer.
How do I calculate my overall grade in a class?
The Class Grader calculates individual test and quiz scores. It shows each student’s percentage and letter grade for a single assessment. To calculate an overall class grade across multiple assignments with different weights, you need a syllabus grader.
Do I need to enter student names?
No. Names are optional. You can paste a plain list of wrong answer counts — one number per line — and the tool labels results Student 1, Student 2, and so on. To add names, use the format Name: Wrong Answers (example: Maria: 3). Both formats work in the same input field and can be mixed in the same list.
How many students can I grade at once?
Up to 100 students per calculation. For most K–12 classroom teachers this covers a full day’s grading in one operation. If you teach multiple class sections, run each section separately and download the CSV for each. The file saves with all student names, scores, grades, and the class average included.
What does the class grader show after I click Grade Whole Class?
The results include a summary bar showing total students, class average, number passing, and top score — the four numbers teachers most commonly need to report. Below that, the full results table shows each student’s wrong answers, correct answers, percentage score, letter grade, GPA, and pass/fail status. A grade distribution chart shows how many students received each letter grade.
Can I download or export my class grades?
Yes. Click Download CSV after grading your class. The file includes every student’s name, wrong answers, correct answers, score percentage, letter grade, GPA, and pass/fail status. A class average row is appended at the bottom. The CSV imports directly into Canvas, Blackboard, PowerSchool, Infinite Campus, and Google Sheets without reformatting.
What is the grading table and how do I use it?
The grading table or quick grading chart, shows every possible score for your specific test size. It lists wrong answers from 0 to the total, with the corresponding correct answers, percentage, letter grade, GPA, and pass/fail for each. Click View Grading Chart after entering your total questions to generate it. Teachers use this as a reference sheet while physically grading a stack of papers.
What grading scale does the Class Grader use?
You can choose from three scales before grading. Standard 10-point: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%. Plus/Minus: A+ = 97–100%, A = 93–96%, A− = 90–92%, and so on down to F. Pass/Fail: 60% and above = Pass, below 60% = Fail. The selected scale applies to every student in the batch simultaneously. Standard 10-point is the USA default and is pre-selected when the tool loads.
Is the class grader accurate for grades computation?
Yes. This whole class grading tool uses a fixed mathematical formula for every student: (Total Questions − Wrong Answers) ÷ Total Questions × 100 = Score Percentage. That percentage is mapped to the selected grading scale to assign a letter grade and GPA. The grades computation is identical for every student without rounding inconsistencies and manual errors. The same formula runs for 5 students or 100 students in the same calculation.
Does the Class Grader support partial credit or decimal scores?
Yes. The total questions field accepts decimals, so tests with partial credit (for example, 22.5 out of 25) calculate correctly. Enter the decimal total in the Total Questions field and whole-number wrong answers for each student. The percentage rounds to one decimal place in the results
Is the Class Grader free and does it require a login?
Yes, it is completely free. No account, no signup, and no download required. Open the tool, enter your data, and grade your class. Results and CSV downloads are available immediately without any registration.
Can I use this as an online grader for teachers on mobile?
Yes. The class grading calculator is fully mobile-responsive and works on phones, tablets, and desktops. The text area accepts pasted lists on mobile, results display cleanly on small screens, and the CSV download works on all devices. Teachers who grade at home, during a commute, or on a tablet during a free period can use it exactly as they would on a desktop.
