Hello Sampriti,

Yes, you can switch from a state board to the CBSE board after failing in class 12th. You will need to apply for admission to a CBSE-affiliated school in class 12 or class 11, depending on the school's policy. You may also need to provide your previous academic records and meet the school's admission criteria.
