This guide explains the cbse grading system for class 10 and cbse grading system class 12 in complete detail
What Is the CBSE Grading System?
The CBSE grading system is a 9-point relative grading scale used to evaluate student performance in Class 10 and Class 12 board examinations. Instead of ranking students purely on raw marks, CBSE uses a relative grading approach, meaning grades are assigned based on how a student performs compared to all other students who appeared in the same subject.
This system was introduced to reduce unhealthy competition, ease exam anxiety, and shift focus from rote memorisation to genuine understanding. Rather than showing exact marks and percentages on the final marksheet, the cbse 10th grading system and Class 12 grading system display grades and grade points for each subject.
CBSE 9-Point Grading Scale: Marks to Grade Conversion
Grades in CBSE are divided into eight segments for passed students and one for failed students. Below is the standard marks-to-grade reference chart used across both Class 10 and Class 12:
| Marks Range (%) | Grade | Grade Point | Meaning |
| 91 – 100 | A1 | 10.0 | Outstanding |
| 81 – 90 | A2 | 9.0 | Excellent |
| 71 – 80 | B1 | 8.0 | Very Good |
| 61 – 70 | B2 | 7.0 | Good |
| 51 – 60 | C1 | 6.0 | Above Average |
| 41 – 50 | C2 | 5.0 | Average |
| 33 – 40 | D | 4.0 | Pass |
| 21 – 32 | E1 | — | Fail (Compartment eligible) |
| 0 – 20 | E2 | — | Fail |
How Relative Grading Actually Works
A key feature of the cbse grading system class 10 and Class 12 is that it is positional, not absolute. Here is how CBSE awards grades:
- All students who have passed in a subject are arranged in rank order based on marks.
- The top 1/8th of passed students receive A1 grade. The next 1/8th receive A2, and so on, down to grade D.
- Slight adjustments may be made to resolve ties, if students have the same score, they receive the same grade. If splitting a tied group is needed, the smaller group is combined with the larger adjacent one.
- This method applies to subjects with more than 500 passing candidates. For subjects with fewer than 500 passing candidates, CBSE follows grading norms from similar subjects.
This is why a student can score the same marks in two different subjects but receive different grades, because grade boundaries shift based on the performance of all students in each subject individually.
CBSE Grading System for Class 10: Key Details
The cbse grading system for class 10 evaluates students across two main components:
| Component | Marks | Details |
| Theory Examination | 80 marks | Written board exam; competency-based, objective, short & long answer |
| Internal Assessment | 20 marks | Periodic tests, notebooks, subject enrichment, project work |
| Total | 100 marks | Aggregate of both components determines grade |
For Class 10, CBSE does not require students to pass theory and practicals separately. The aggregate of the theory exam (80 marks) and internal assessment (20 marks) must together meet the 33% passing threshold. This is a key difference from Class 12.
Additionally, CBSE uses a separate 5-point grading scale (A to E) for co-scholastic subjects such as Art Education and Health & Physical Education. Students must score above Grade E in all internal assessment subjects to be declared pass.
CBSE Grading System for Class 12: Key Details
The cbse grading system class 12 follows the same 9-point scale but with one critical difference in the passing requirement. For Class 12, students must pass theory and practicals separately:
| Component | Marks | Minimum to Pass |
| Theory Examination | 70–80 marks (varies by subject) | 33% in theory separately |
| Internal Assessment / Practical | 20–30 marks (varies by subject) | 33% in practical separately |
| Overall Aggregate | 100 marks | 33% overall aggregate required |
Scoring 33% overall but failing theory or practical individually will still result in a compartment status. CBSE has also stopped releasing merit lists or toppers lists for Class 12 to discourage unhealthy competition. Instead, Merit Certificates are issued to the top 0.1% scorers in each subject.
What Is CGPA and How to Calculate It?
CGPA stands for Cumulative Grade Point Average. It is the average of grade points earned in the five main subjects and gives an overall measure of a student’s performance.
Formula: Add the grade points of the top five main subjects and divide by 5.
Example: If a student scores grade points 10, 9, 8, 9, and 9 in five subjects, the CGPA = (10+9+8+9+9) / 5 = 9.0
To convert CGPA to an approximate percentage, multiply by 9.5:
Percentage = CGPA × 9.5
| CGPA | Approximate Percentage |
| 10.0 | 95% |
| 9.0 | 85.5% |
| 8.0 | 76% |
| 7.0 | 66.5% |
| 6.0 | 57% |
Note: This is an indicative conversion. CBSE marksheets do not display an exact percentage, only grades and grade points are shown officially.
Benefits of the CBSE Grading System
- Reduces cut-throat competition by not displaying exact marks on the final marksheet.
- Promotes holistic learning, internal assessments, projects, and practicals are given equal weight.
- Fairer evaluation through relative grading, which accounts for subject-level difficulty variations.
- Reduces exam stress by focusing on grade bands rather than single marks.
- Uniform grading ensures consistency across all CBSE-affiliated schools in India and abroad.
Frequently Asked Questions (FAQs)
Q1. Does CBSE show exact marks or only grades on the Class 10 marksheet?
The official CBSE Class 10 marksheet displays grades and grade points for each subject, not exact marks. However, for Class 12, subject-wise marks are shown alongside grades. Students may request a marks conversion certificate from their school or CBSE regional office if needed.
Q2. Can two students with the same marks get different grades in the cbse 10th grading system?
Yes, this is possible. Because CBSE uses relative grading, grade boundaries are determined by the rank distribution of all students in a particular subject. The same marks in different subjects may fall in different grade bands depending on how other students performed in those subjects.
Q3. What does A1 grade mean in CBSE Class 10 and 12?
A1 is the highest grade in the CBSE grading system, carrying a grade point of 10.0. It is awarded to students who fall in the top 1/8th of all passed candidates in that subject. Typically, this corresponds to marks in the range of 91–100%.
Q4. Is the CGPA formula the same for both Class 10 and Class 12?
For Class 10, CGPA is calculated using the grade points of the five main subjects. For Class 12, the grading is subject-wise and the CGPA formula is similar, sum the grade points of all subjects and divide by the number of subjects. Multiply CGPA by 9.5 to get an approximate percentage for both classes.
Q5. What happens if a student scores Grade E in the cbse grading system class 12?
Grade E indicates failure. In Class 12, E1 (marks 21–32) makes a student eligible for the compartment exam in that subject. E2 (marks below 21) is a fail without compartment eligibility. Failing in one subject leads to compartment status; failing in two or more subjects results in Essential Repeat (ER) status, requiring the student to repeat the year.
