Hello.

Sorry, but it is not possible to change your board from MP to CBSE in class 11th. As your registration process is done in class 11th only, hence it is difficult to change boards in class 11 itself. And if you do so then you cannot continue as a regular student. It is also not advisable to change board in 11th class as a change in board would also mean change in course which could be too burdening for you as you have to acquaint yourself with course once again.
