CBSE Grading System Explained: Grades, Marks & Percentage
Quick Answer
The CBSE grading system uses subject-wise grades along with marks for Class 10 and Class 12 Board Examinations. CBSE follows relative grading rather than fixed mark ranges for grades. Passed candidates are arranged in rank order and divided into groups, while percentage calculation is not declared by CBSE itself.
Quick Overview
| Thing | Why it matters |
| Relative grading | Grade depends on subject-wise candidate performance |
| A1 to D2 | Grades are awarded to passed candidates |
| Grade E | Indicates essential repeat status |
| Marks and grades | Both appear in the marksheet |
| Percentage | CBSE does not calculate it |
| Class 10 and 12 | Grading applies to both Board Examinations |

What Is the CBSE Grading System?
The grading system in CBSE is not simply a fixed table where a particular mark range always produces the same grade. CBSE’s 16 May 2024 notification explains that the Board uses relative grading for subject-wise grades in Class X and XII examinations.
In simple terms, the grade depends on how candidates perform in that particular subject. So, the same marks can potentially lead to different grades in two different subjects because the number and relative performance of candidates can differ.
That is why old internet tables showing fixed marks against A1, A2, B1 and other grades should not automatically be treated as current CBSE rules.
Action point: When checking a grade rule, look for an official CBSE notification instead of relying on a familiar marks table.
How CBSE Grades Are Awarded
CBSE places passed candidates in rank order for each subject and divides them into eight groups. Each group represents one-eighth of the passed candidates. Ties can lead to minor adjustments so students receiving the same score receive the same grade.
CBSE Grade Chart and Grade Meaning
| Grade | CBSE’s relative position |
| A1 | Top 1/8 of passed candidates |
| A2 | Next 1/8 |
| B1 | Next 1/8 |
| B2 | Next 1/8 |
| C1 | Next 1/8 |
| C2 | Next 1/8 |
| D1 | Next 1/8 |
| D2 | Next 1/8 |
| E | Essential Repeat |
The important detail here is what the table does not say. It does not assign a permanent percentage range to each grade. The 2024 CBSE notification specifically says the grades are based on the relative merit of candidates and can vary from subject to subject.
Action point: Treat this as a relative CBSE grade chart, not as a marks-to-grade conversion table.
Important: Two students with identical marks in different subjects do not necessarily receive the same grade. CBSE says grading depends on the number of candidates passing the subject and their relative scores.
CBSE Grading System Class 10 – H2
For CBSE grading system class 10, the same relative-grading principle applies to the Class X Board Examination. CBSE’s 2024 notification covers subject-wise grades for both Class X and XII and says the awarded grades are reflected along with marks in the marksheet-cum-certificate.
There is also an important recent change to the examination structure. CBSE introduced two Board Examinations for Class X from 2026, so students should check the instructions applicable to their particular examination session rather than using older Class X guidance.
For students, the practical takeaway is simple:
- Check the marks shown for each subject.
- Check the corresponding grade.
- Do not assume the grade came from a fixed percentage bracket.
- Use the examination-year rules when checking pass or result-related questions.
Action point: If you are checking a 2026 Class X result, use the latest CBSE notices rather than an older grading article.
CBSE Grading System Class 12
The CBSE grading system class 12 also follows the relative-grading approach described by CBSE. The Board’s notification applies the method to subject-wise grades in Class X and XII.
Class XII students often run into another issue when filling college or employment applications: a form may ask for a percentage even when the Board itself has not calculated one.
CBSE’s percentage notice states that the Board does not calculate, declare or inform the percentage of marks. If a percentage is required for higher education or employment, the admitting institution or employer may determine how it should be calculated.
Action point: Follow the percentage requirement given by the specific college, university, employer or application authority.
Marks, Grades and Grade Points
Students often search for CBSE grade calculation or a CBSE marks to grade formula because they expect one fixed calculation. That assumption does not match CBSE’s current relative-grading explanation.
CBSE’s 2024 notification describes the ranking-based process but does not provide a universal marks-to-grade formula. It also explains that where fewer than 500 candidates pass a subject, grading follows the pattern and distribution of similar subjects.
This is also why older references to the CBSE CGPA grading system can create confusion. CGPA-based information from earlier CBSE frameworks should not automatically be applied to the current Board result system.
Action point: Do not calculate a grade yourself from an old grade-point table unless the relevant CBSE document for that examination specifically requires it.
Can a CBSE Grade Be Converted to Percentage?
There is no single current CBSE formula that converts every grade directly into an exact percentage.
The phrase CBSE grade to percentage is therefore slightly misleading when it suggests that A1, A2 or another grade has one fixed percentage equivalent. CBSE’s official notice says the Board does not calculate or declare the percentage.
For students who need a percentage for admission, scholarships, employment or another application, the organisation receiving the marks may specify its own calculation method.
Action point: Before converting anything, read the instructions of the institution asking for the percentage.
Passing Criteria and Result Status
The CBSE passing grade should not be confused with the grade that a student considers “good” or “low.” Passing requirements and grade distribution serve different purposes.
CBSE’s published examination rules specify qualifying requirements for Board subjects, while current examination notices and subject-wise instructions should be checked for the applicable examination year. The Board’s official examination pages continue to publish current Class X and XII examination material.
The term CBSE result grading system is often used broadly online, but a result contains more than the letter grade. Students should check the marks, grade and result status shown in the official document.
Action point: For a pass/fail question, check the current examination-year rules instead of judging the result from the letter grade alone.
Common Misunderstandings About CBSE Grades
A few assumptions keep appearing in student discussions, especially when older grading articles are copied from one website to another.
| Common assumption | What the official information says |
| A1 always equals a fixed mark range | Grades are based on relative performance |
| Every grade has one percentage equivalent | CBSE does not declare a universal conversion |
| Same marks always mean same grade | Subject-wise relative performance matters |
| Old CGPA formulas apply everywhere | Check the current examination requirements |
| CBSE calculates every student’s percentage | CBSE says it does not calculate percentage |
The CBSE grading criteria should therefore be read in the context of the particular examination year and official notification.
Action point: If an online table conflicts with an official CBSE document, use the official document for the relevant examination.
How to Read a CBSE Marksheet
A marksheet can look straightforward until a student tries to use it for admission or another formal application. Start by checking the subject-wise marks and grades rather than trying to turn every grade into a percentage.
CBSE’s 2024 grading notification states that subject-wise grades are awarded along with the marks secured in each subject and reflected in the marksheet-cum-certificate for Class X and XII.
If an application asks for an overall percentage, check its instructions before doing any calculation. CBSE’s own percentage notice specifically leaves such calculations to the admitting institution or employer where a percentage is required.

Conclusion
The CBSE grading system is easier to understand once grades and percentage are treated as two separate issues. CBSE uses relative grading for subject-wise grades, while it does not calculate or declare a student’s percentage. For Class 10 and 12, students should rely on the official examination-year information before interpreting grades, passing status or percentage requirements.
FAQs
What is the CBSE grading system?
The CBSE grading system awards subject-wise grades to Class X and XII Board Examination candidates along with their marks. CBSE uses relative grading, where passed candidates are placed in rank order and divided into groups rather than being assigned grades through one fixed marks range.
How does the CBSE grading system work for Class 10?
Class X subject grades are based on CBSE’s relative-grading method. The Board ranks passed candidates within a subject and distributes them across eight groups. Students should also check the examination-year instructions because Class X examination arrangements have changed from 2026.
How does grading differ for Class 12?
The relative-grading method also applies to Class XII Board Examination subjects. The key point is that grades are subject-wise and depend on the relative performance of candidates in that subject. Percentage requirements for college or employment applications may be handled separately by the organisation concerned.
What do CBSE grades mean?
CBSE uses grades from A1 through D2 for passed candidates, with E listed as Essential Repeat in its 2024 grading notification. A1 through D2 represent successive groups of passed candidates according to their relative performance in a subject.
How are CBSE grades calculated?
There is no simple formula in which a fixed number of marks automatically produces a particular grade. CBSE uses relative grading, placing passed candidates in rank order and dividing them into eight groups. The distribution can vary by subject because candidate numbers and relative scores differ.
How can a CBSE grade be interpreted in percentage terms?
A CBSE grade should not automatically be treated as an exact percentage. CBSE’s official notice says it does not calculate, declare or inform percentage. When a percentage is needed for admission or employment, the receiving institution or employer may specify how it should be calculated.
What is the passing grade in CBSE?
Students should not decide pass status simply by looking at a grade label in isolation. Passing requirements depend on the applicable Board examination rules and subject conditions. For current results, students should check the official CBSE examination information for their examination year.
Where should students verify the latest CBSE grading rules?
Students should use the official CBSE website, particularly its examination circulars, examination bye-laws and current marking or examination information. CBSE continues to publish examination notices and updates, so older school blogs and copied grade tables may not reflect the rules applicable to a current examination.
