Dear Student,

Don't even think about it because in that way you will lost your OBC Candidature and you will be counted as General student after that.

You need to renew Caste and other certificates they are asking because if you put th eold certificates with the edited dates and after matching if they found that then they will; cancel your candidature, because everything is cross checked in the counselling. Don't even try to this mistake just apply for the new certificates as soon as possible.

Good Luck:)
