You can change your CGPA marks to percentage as well.

1. For average CGPA:

Sum of all the Grade Points (GP) of each subject must be divided by 5.

For instance, if an examinee scores the GP for- Subject 1 is 8, Subject 2 is 9, Subject 3 is 9, Subject 4 is 9.5 and Subject 5 is 7

Then the sum of GPs will be: 8+9+9+9.5+7= 42.5

Dividing 42.5 by 5, we get 8.5 which is the aggregate CGPA.

2. For overall indicative percentage of marks:

We need to multiply CGPA with 9.5. (9.5*CGPA)
