Good luck

Hello aspirant. No. Not necessarily. It's not a compulsion that both jee and +2 Mark's are needed to enter sastra. There are 2 streams where stream 1 takes jee mains and +2 mark, stream 2 takes +2 Mark's alone . You can try through that

But if you aiming through stream 2 , make sure you get really good score
