Hello,

Generally for CBSE board exam, they have a formula for converting cgpa to percentage that is they have  to multiply their grade  with 9.5 to obtain percentage. But for Andhra Pradesh and Telanagana there is no such kind of formaules to convert grade to percentage. Therefore, you need to multiply your grade with 10 in order to obtain percentage. Since you have got 9.8 Cgpa so your percentage will be 98%.

You percentage lies in the range of 90-100%. Now to calculate the percentage you must know the marks you get in particular subjects. But if we roughly estimate your percentage can be 93.1-95%.

I hope my answer helps you. All the very best for your future endeavors!
