Hello,

You haven't mentioned which exam you are asking about.

On the part of question. there is no addition on the qualification in +2 from science stream. All students have that qualification. So it is not additional.

You can visit the official webpage of the board and check for the eligibility and check if you are satisfying it or not. If you are then you can apply for it

Please mention the exam name below in the comment section so that i can answer you precisely whether it makes you eligible or not.

Hope it helps!
