• Encourages balanced learning: By shifting focus from marks to skill development, CGPA promotes creativity, communication, and critical thinking.
• Globally aligned: The CGPA system aligns with international grading models, making it easier for students to apply to universities abroad.

CBSE Grading Scale for Class 10

CBSE uses a 9-point grading system to evaluate student performance in Class 10, replacing raw marks with grade points. This scale promotes fair and stress-free assessment by grouping students based on their score ranges instead of exact marks.

Below is the official CBSE Grade-to-Marks-Range mapping:

How to Calculate CGPA in CBSE Class 10?

The CGPA (Cumulative Grade Point Average) is calculated by taking the average of grade points obtained in the five main subjects (excluding any additional subject). It gives a quick overview of a student’s academic performance in a simplified, stress-free format.

Steps to Calculate CGPA:

• Add the grade points of the five main subjects.
• Divide the total by 5 (since there are 5 main subjects).

Example:

CGPA = Total Grade Points / 5 = 45 / 5 = 9.0

How to Convert CGPA to Percentage?

If you’re looking for a CGPA to percentage converter, here’s the standard method prescribed by CBSE to calculate it manually:

Percentage (%) = CGPA × 9.5

This simple formula helps you convert your CGPA into an approximate percentage score.

Example:

If your CGPA is 9.0,

then Percentage = 9.0 × 9.5 = 85.5%

So, no need to search around, just multiply your CGPA by 9.5 and you’ve got your percentage!

Why is 9.5 used in CGPA to Percentage Converter?

The multiplier 9.5 was introduced by CBSE after conducting a detailed analysis of student performance data over a five-year period. Here's how the board arrived at this specific figure:

• Top Percentile Analysis: CBSE focused on students scoring between 91 and 100 marks—the top performance bracket that corresponds to Grade A1 with a GPA of 10.
  
  
• Average Marks Estimation: Across this group, the average score was found to be approximately 95 marks.
  
  
• Conversion Factor Derivation: To translate CGPA into a percentage, CBSE divided the average marks (95) by the GPA (10), resulting in the conversion factor:
  
  95 ÷ 10 = 9.5

This formula ensures a standardized and fair method of converting grades into percentages for official and academic use, especially useful during college admissions, scholarships, or competitive exams.

How to Calculate Overall Percentage in CBSE Class 12?

For Class 12, CBSE provides subject-wise marks directly. To calculate the overall percentage, students can follow these steps:

Step 1: Add the marks of all main subjects (usually 5).
Step 2: Divide the total by the number of subjects.

Example:

Percentage = 450 / 5 = 90%

With CBSE Result 2025 around the corner, knowing how to convert CGPA to percentage or calculate your overall percentage is crucial for admissions and documentation.
