Dear Aspirant,

You have not specified your situation completely. However, according to the information you provided, the minor problems will be like there is something which is non readable,etc. If such type of problem arises and that too after the completion of process, then the authorities might give you some time to produce a new document without any such problem.

While on the other hand if the problem os of bigger nature like it is the central OBC certificate that is required and you have the state's certificate, or the certificate is expired a long time ago, then this might lead to no reservation and you'll be evaluated as a general category student.

Hope this helps. Thank you.
