Hi Aspirant,

Hope you are doing great as per the question asked by you as you have made mistake while filling up the form you should definitely mail to the required authorities regarding the mistakes you have made sometimes correction window is given to the students to correct the mistakes if made any during the process else it is not very big mistake you can certainly upload or submit the central O.B.C N.C.L certificate at the time of counselling or admissions .

Hope you found this answer useful.Stay motivated stay positive.

All the best!
