Nope! Biology isn't compulsory in 11th. Its your choice you can have Biology or Not. So from 11th you are free to choose the subject you want. Obviously, the subject you choose must be present in the school or junior college you take admission in.

In Hindi:

nahin! 11veen mein biology anivaary nahin hai. yah aapakee marjee hai ki aap biology le sakate hain ya nahin. isalie 11veen se aap manachaaha vishay chunane ke lie svatantr hain. jaahir hai, aapake dvaara chuna gaya vishay us skool ya jooniyar kolej mein maujood hona chaahie jisamen aap pravesh lete hain.

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