Understanding the CGPA Grading system

Cumulative Grade Point Average (CGPA) is an essential measure of your performance in school or college. It is calculated up to two decimals. It is the average of all your grades in all subjects. To check your CGPA, take the sum of all grade points of your subjects and divide by the number of subjects.

Origin of CGPA

The professor of Cambridge University, Willian Farish, created the grading system, including CGPA, in 1972 in England. The reason for introducing this system was to understand student learning and evaluate performance more appropriately.

Benefits of the CGPA System

Cumulative Grade Point Average (CGPA) can be very helpful when applying to colleges and universities, especially abroad. The following are some of the key benefits of the CGPA system:

Identify Your Strengths and Weaknesses:

CGPA helps to determine which subjects you are good at and need to work on so that you can concentrate on improving your weaknesses and building on your strengths.

Reduces Pressure:

It will reduce the pressure because your report card shows the overall grade instead of the marks. This will help you focus more on achieving good grades and be less stressed about getting higher marks.

Modern Grading Pattern:

CGPA calculates exam scores and performance in assignments, attendance, and other accomplishments, providing a more complete picture of your abilities.

Simplified Study Pattern:

Focusing on overall performance rather than just focusing on marks can help students gain good grades by participating in different activities and excelling in additional areas.

Promotes Comprehensive Teaching:

CGPA plays an essential role in identifying students who are weak, average, or firm. It enables teachers to give extra attention and support to those who need it most, helping everyone improve.

Conversion of CGPA to percentage

Steps to Convert CGPA to Percentage

  1. Add the grade points for all your subjects.
  2. Divide the total of grade points by the number of subjects. This gives you your CGPA.
  3. Multiply CGPA by 9.5 to check the percentage equivalent.


If the sum of your grade points is 45 and you have 5 subjects:

  1. Total grade points = 45
  2. CGPA = Total grade points / Number of subjects = 45 / 5 = 9
  3. Percentage = CGPA × 9.5 = 9 × 9.5 = 85.5%

The Central Board of Secondary Education (CBSE) uses a 10-point scale to grade students.

Converting CGPA to Marks

 To convert your CGPA to marks, you can use the following formula:

Marks = (CGPA×9.5×Sum of Maximum Marks of Each Subject)/100


If your CGPA is 8 and the sum of the maximum marks for all subjects is 500:

Calculate Marks:




So, you have 380 marks in total.
