See if you get your SC certificate then you have applied for it right? Now when you have applied for it, then obviously you must be in the category of SC or else the certificate wouldn't be issued to you. So its for sure that you belong to the category or else how can the Magistrate or the SDO or the authority can issue it. Now why you mean wrongly, is a concern to us. So I would recommend you to elaborate more about the problem and repost the question on career360.com (//career360.com) so that we can understand the entire scenario and give you the necessary information.

Have a great day!
