In CBSE Class 12 , students typically have five main subjects and can opt for one additional subject. Among your listed subjects, English, Physics, Chemistry, Mathematics, either Hindustani Music or Painting would constitute your five main subjects. You must choose one of these as an additional subject. Therefore, you would choose either Hindustani Music or Painting as your additional subject, while English, Physics, Chemistry, and Math remain your core subjects. The benefit of choosing an additional subject like Hindustani Music or Painting lies in its potential to enhance creativity and cultural appreciation alongside studying regular academic subjects.
