Hello ManojKumar, yes in the upcoming days with the  help of school authority you will be able to change it.

thanks!

Hey aspirant, It depends upon your board as if you appeared in class 11th from other school and 12th location of school was different then might be the same school and its location was different and the registration which was done in 11th will go same in class 12th. So you first need to know that whether it was the same school and branches different.

Hope this helps

Good luck
