Hello student ,

Here i would like to inform you that if you have bubbled your wrong roll number then computer will captured your right roll number by that omr sheet reader and your result will be declared accordingly to that only . Further if you want to make more clarification then you should write your this issue on the NTA website so that ypu can get more clarification . Else i will suggest you to don't take tension your result will be declared .

Hope it helps !
