i am a student of class 10 in a school affiliated to cbse. it is compulsory for us to give the board exams. i want to change my school in class 11 to another cbse affiliated school. but i have heard that if i give boards in class 10, then i cannot change my school in class 11 and if i do so, then i will have to go to a non cbse affiliated school. is it true ?? if yes, then how can i change my school ?
