Hi Aspirant,

Given the conditions you described above , you may not be able to give 12th board exams again from CBSE after this gap. So I would suggest you to apply for the board exam from your native state board. You may get a chance there to give your 12th board exams(given that you satisfy the eligibility conditions).

Refer the link below to get more information about your state board,

Hope this helps. And don't loose hope because there's always a second chance for everyone.

Good luck!!!
