hello ,

I have gone throughout your query and here you are HINDU OBC and you converted to a CHRISTIAN  group that is a general category so mention  GENERAL category as you converted and your category into GENERAL.  Also consider, you can get your caste changing documents while filling your UGC NET examination. As your new category is GENERAL which is final.

Hope you understand what I am trying to say. In case of any query about this, you can comment below.

Thank you  and good luck:)
