What is the CBSE Grading System?
CBSE (Central Board of Secondary Education) uses a 9-point grading scale instead of just marks. This system evaluates student performance more holistically:
- Grades: From A1 (highest) to E (fail)
- Grade Points: Numerical values (0-10) used to calculate CGPA
- CGPA: Cumulative Grade Point Average across all subjects
This converter helps students instantly see where they stand and what they need to achieve their target grade.

How to Calculate CGPA
CGPA (Cumulative Grade Point Average) is calculated across all subjects:
Example: If you get grades A1 (10), A2 (9), B1 (8), B2 (7) across 4 subjects:
CGPA = (10 + 9 + 8 + 7) ÷ 4 = 8.5
| Percentage Range | Grade | Grade Point | Status |
|---|---|---|---|
| 91–100% | A1 | 10 | Pass |
| 81–90% | A2 | 9 | Pass |
| 71–80% | B1 | 8 | Pass |
| 61–70% | B2 | 7 | Pass |
| 51–60% | C1 | 6 | Pass |
| 41–50% | C2 | 5 | Pass |
