Hello Raj kumar

I hope you are doing good. I would like you tell you that only applicant certificate is required at the time of counselling , But i advise you that you should have all the valid certificates so at time of counselling their wont be any pressure if they ask for any certificate because every year rules are supervised . Their is no harm in making your father certficate ,You can get this issued nearby SDM office in your district. Secondly you have to show your income tax certificate  as a proof at the time of issuing SC certificate , so scholarship thing doesnt matter you should have your income certificate with you

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