Hello aspirant,

You have also admitted as General Category candidate then now you cannot change it to OBC Category.

As you did not got your OBC Category Certificate, so you joined the College as General Category candidate. Now you cannot change it most of the cases it is not possible.

Now though you have the certificate you might not get chance to change your caste, once talk to the College authorities about it.

May this information was helpful to you.

All The Best!!
