Hello tapan

I hope you are doing good . As per your query , I would like to inform you that for availing 15.5 percent reservation beneffits of SC category you need to have SC certifcate from centre and your caste should be on SC-central list . If your Caste is listed on SC -central list then their are chances that you dont need to get it centralized but for a safe side try to get it centralized

Hope you found this answer helpful. Good luck for your future
