I have done 12th up board from biology.Can I also doing it with math and also keep my biology?Can I apply now if not Can I do it as a private candidate after one year drop?
Yes, you can definitely re-admit yourself as a private candidate and study maths. Your biology marks will also be considered. However, you will get a different marksheet for maths subject. In other case, you can apply for the course via open university such as NIOS etc.,
Hope this helps.
