Reappearing in board exams is a big decision and due to dissatisfaction of marks its more big as you lose 1 year of your career in repeating same class again. But as you want to do the same so its very easy to reappear in board exams. You can either reappear as a private candidate or regular candidate by enrolling once again in your school for boards. But first think properly about reappearing in Board exams if you are fully sure with your decision then go ahead and do best. Rest is your decision.
I hope this will help you.
