Hello Sulekha Kumari,

As you have mentioned that you have opted PCB with maths as an elective. So here you can calucalte your best four aggregate percentage including English as a language subject ,Physics,chemistry and further you have to add any of the maths or bio based on the you will opt . For eg. if you are opting BSC so your maths marks will be consider and if will any bio related course then your bio marks will be added to the agrregate of best four.

Hope it helps.

Thank you.
