If you belong to any of these then you must select them for your benefit

The terms Economically Weaker Section (EWS) and Economically Backward Class (EBC) are not meant to be confused with each other in India.

One have to get the OBC certificate in a prescribed form from state Authority by producing the pay slip of family income.
