YES ABHILASH,

                        If you belong to any category except general,THEn its mandatory for you to show the caste cretificate in the physical reporting centre or else your seat would be cancelled.

Hope this helps you.

Dear Student,
Glad to inform you that Caste Certificate is not mandatory for attending the counseling session but you need to have and provide caste certificate if you want to be benefitted by the Caste based quota if any. If from general category or if you don't wish to get admissions through quota you can appear without a certificate without any problem.
Hope this might help you.
