Hello Aspirant

No, you cannot miss your fourth subject's exam. In fact, you cannot miss any exam in your 12th grade Board examinations. If you do, you will be deemed to fail in your examination and will not get your TC, Migration, Character Certificate, or Mark sheet. As a result of this, you will not be able to get admission to any college/university for your Bachelor's.

No matter if it is your main subject or an extra subject that you chose or an elective, you have to appear for all the subject exams that have been mentioned in your Admit Card. Kindly do not miss any exam of the 12th board or else you will have to sit at home for a year so that you appear for the exam again the next year.
