Hello student ,

As of now both the CBSE and CISCE have planned to postpone the board examination to May 2021 .The examination of both the boards usually held in March. The Delhi government recently wrote to the CBSE, urging it not to conduct the board exams next year before May . However, the final decision would be taken only after the directives from the Education Ministry. So i will suggest you to keep taking update .

Hope it helps !
