How to calculate CGPA?

The Central Board of Secondary Education (CBSE) has a curriculum where five subjects are compulsary and one is optional.


Assume the grade points of the 6 subjects as
Sub-1, Sub-2, Sub-3, Sub-4, Sub-5, Sub-6
Grade point(GP)=Sub-1 + Sub-2 + Sub-3 + Sub-4 + Sub-5 + Sub-6
CGPA = Grade point / 6

Subject 1 Grades= 10
Subject 2 Grades=9
Subject 3 Grades=10
Subject 4 Grades=8
Subject 5 Grades=10
Subject 6 Grades=9
Grade point = 10 + 9 + 10 + 8 + 10 + 9
Grade point = 56
CGPA = 56 / 6
CGPA = 9.3


Percentage = (CGPA x 9.5)
CGPA = 9.3
Percentage = 9.3 x 9.5
Percentage = 88.35%


CGPA = (Percentage / 9.5)
Percentage = 85.1
CGPA = 85.1 / 9.5
CGPA = 8.9
