Hello sir/Madam,
This is in regard with the rules of cbse for a change of subject in class 12.I would like to know if a student who has studied "computer science" in class 11 and wishes to change his subject from computer science to Physical Education or Informatics Practices in class 12,Is it possible?If yes, what is the procedure?
Please treat this as most urgent.

Waiting for the reply.
Thanks & regards,
