Sir I have uploaded worng OBC NCL in my JEE ADVANCED form (only the purpose of making the cretificate is wrong, mentioned that it is made for Government vacancies), but now I have a new and OBC NCL of the correct format so in JOSAA should I upload the new OBC NCL certificate which is correct?
UPDATE: B.Tech applications open at Manipal Institute of Technology Apply Now
Yes, you should upload the original OBC certificate in JoSAA portal in order to avoid problems during admission. I don't think there will be any problem if the certificates don't match. They will definitely consider the new one. Make sure to submit the correct document during admission to the college.
All the best.
