I am arts student in 12th but I really want to be a doctor so I can join open school in 11th science stream is that possible
If you want to become a doctor but you're now in 12th arts, all you have to do is restart your 11th class all over again with bio science stream.
You can do it from nios or you can write a application to your school regarding the fact.
My suggestion would be go to a nios take up science stream.
yes you can join 11th science in nios if you do not want to continue studying arts,
