Dear aspirant,



According to your query,



You can do this.  You can change your category by submitting the valid and verified latest caste certificate or any other document related to your caste verification held online. All you need to do is to visit official website of counselling session ( where you did your document verification earlier)  and refill your details accordingly.



Hope you find it useful.



Thank you.
