Dear student,

As you have obtained 9.8 GPA in class 12th as per Andhra Pradesh IBTER Board. The CGPA will be 9.8 for class 12th and 9.2 for class 11th as it remains separately. For admission in colleges only class 12th CGPA is evaluated because it is obtained after calculating GPA received in every subject and dividing it by the total number of subjects so it is called Cumulative Grade Point Average. Hope this helps!
Best Wishes!
