Understanding CGPA and Percentage Conversion for Class 10 and 12 Students

Introduction to CGPA and Its Importance


In Class 10, students receive a CGPA (Cumulative Grade Point Average) instead of traditional marks. However, in Class 12, marks are awarded for each subject. When applying for college admissions, scholarships, or filling out government forms, it is often necessary to convert CGPA into a percentage. Let’s explore how to convert Class 10 CGPA into a percentage and calculate the overall percentage from Class 12 subject marks.


What is CGPA and How is it Calculated?

Understanding CGPA Calculation



  • English – 9


  • Mathematics – 10


  • Science – 9


  • Social Science – 8


  • Hindi – 9



To find the total grade points: 9 + 10 + 9 + 8 + 9 = 45


Now, to calculate CGPA: 45 ÷ 5 = 9.0, indicating that the student's CGPA is 9.0.


CGPA represents the average score of students and is specifically designed for Class 10 students under the CBSE board. It is calculated using the grades from five core subjects: English, Hindi, Mathematics, Science, and Social Science. The grade points from each subject are summed and divided by five.


How to Convert CGPA to Percentage?

Conversion Method


According to CBSE guidelines, converting CGPA to percentage (%) is straightforward. Simply multiply the CGPA by 9.5. For instance, if a student has a CGPA of 9.0, the percentage would be calculated as follows: 9.0 × 9.5 = 85.5%. Thus, the student's percentage is 85.5%. This method is based on the average marks of students achieving an A1 grade (91-100 marks), which is approximately 95, leading to the conversion factor of 9.5.


Calculating Overall Percentage in Class 12

Direct Calculation from Marks


In Class 12, CBSE awards direct marks for each subject instead of CGPA, making percentage calculation straightforward. To determine the percentage, add the marks from all main subjects such as English, Mathematics, Physics, and Computer Science, and then divide by the number of subjects. For example, if a student scores a total of 450 marks across 5 subjects, the percentage would be calculated as: 450 ÷ 5 = 90%. This indicates the overall performance of the student.
