Hello Neha!

EBCs are the economically backward classes whose annual income is less or equal to 1 lakh in Bihar state.

The creamy layers of the OBCs, i.e the BC sub category comprises of families that earn more than 1 lakh annually. The EBC category enjoys 18% reservation of all MBBS seats in Bihar.

You said that you applied under unreserved category in NEET exam and appeared as a UR candidate. Hence, you do not hold OBC category rank. Applying through any other caste reservation will cause discrepancies and can push you into trouble .
