I am 12th right now last year I had given physical education exam and now school told me to give computer because they did registration..
But as i can see you had Physical Education in class 11 but due to an error your school has submitted Computers as your 5th subject. You may write an application and get it signed by your pricipal and send it to the CBSE Zonal office of your place/state, clearly stating your condition and the error in subject selection. Since you havent studied computers in class 11, your case would ideally be considered and your subject may be reverted back to physical education.
