Hi there,

If your query is regarding 12th board exam then if you are from commerce stream then you will be studying economics, accounts,business studies,mathematics and English. So, you will have to give exam of only these subjects which are related to commerce stream. You will not have to give any exam related to science stream .

But fom your profile it seems you are an art aspirant. So please clear your query so I can give you more appropriate answer.

Hope it helps you

Good luck!
