Dear Aspirant,
As per your question, yes, it is possible to change your board in class 12th from CBSE to JKBOSE.
For that you firstly need to approach your school authorities, so that they can guide you well and also provide you with all the necessary documents.
Next you need to approach CBSE and provide them with all the relevant documents and paperwork. You also would be required to present a valid reason and a proper explanation as to why you wish to change the board.
After following this process, you'll possibly be able to change your board.
Hope this helps!
