What is CGPA?
CGPA stands for Cumulative Grade Point Average. It is the average of grade points obtained in the five main subjects, calculated on a 10-point grading scale.
CBSE Grading System 2025

The passing grade is D
Students getting grades E1 or E2 need to appear for compartment exams
These compartment exams are usually held about a month after the regular results are out.
Want to understand the CBSE Class 10 grading system in more detail?
The CBSE Class 10 marking scheme for the 2024-25 academic year is made to give a complete picture of a student’s learning. It focuses on how well students understand the subject, how they apply it, and how strong their concepts are.
To convert CGPA to percentage, CBSE uses a simple formula, Standard Formula (10-point scale):
Percentage = CGPA x 9.5
So if your CGPA is 9.2:
9.2 x 9.5 = 87.4
Your percentage is 87.4%.
Why Multiply by 9.5?
CBSE studied the marks of students over the years and found that those who scored between 91 to 100 marks (Grade A1) had an average score of 95.
Since A1 equals 10 grade points, 95 ÷ 10 = 9.5. That’s how the multiplier was decided.
