Hello student ,

You don't need have to worry about this if have filled wrong roll number , you result will be declared if on the top you have filled right roll number . The thing which is happen is that your omr not get read by computer then the operators will checkout your omr and feed your correct roll number in the system and will then  proceeds to result . Further NTA has said that it will take special care if some one will filled wrong roll number in Omr . If you want further clarification then you can mail your to the NTA 's mail address .

Hope it helps !

Dear Aspirant

Thins thing is pretty serious  . First tell me did you bubble right in the the place for roll number in the OMR sheet?

If you bubble right then no problem will occur. The computer reads only the Bubbles and not the handwritten roll number.  So wrong handwritten Roll no will not bring any harm to you. But if there is anything wrong with the bubbling then your answer sheet that is the OMR sheet will be disqualified as the OMR sheet is being checked by the computer.

you try to remember in which part you have done the mistake.

Try to contact the Examination board . Mail NTA

Best Wishes.
