I got 300 marks in neet and having ESI card.eligible for ESI quota but we didn't applied for it before the last date is there any other way

Dear Venkat, if you havent selected ESI Category while filling in the NEET application form, now you cannot change your options. Neither can you claim the ESI quota. The details that you enter while registering for counselling should match with the information you filled in during the NEET application form. Because initially you didnt choose ESI, though you have that quota, you cannot claim it unfortunately.
