Hello,


The mains subjects apart from English which is a core subject and is compulsory, you will have to take accountancy, business studies, Economics and for optional you will have to choose from the options like ( Maths,computer,English,hindi,sanskrit and phe).Its just that you will need to have 5 subjects

You can choose according to your choice.

There are many subject options given by cbse as optional but it depends upon your school that what subject it has taken. The compulsory subjects in class 11th are, English, Business studies, Economics and accountancy. Options that might given to you are mathematics,computer, fashion studies, physical education, entrepreneurship etc.
Thank you.
