If you have IP Quota then you have to appear for All India Counselling and for that you will need atleast 550 because the IP Quota of ESIC Colleges are filled up in Mop up Round. But this is based on previous years data and cut offs change every year. Cut offs chamge every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. So to just answer your question, you will need 550 atleast.

Hi

In neet  2018, 415   marks was the lowest marks that was required for sc category for getting a seat in mbbs in  ESIC Faridabad  under Haryana state quota

But cut off marks for medical colleges keeps changing every year depending upon various factors like number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

So , you should try to get at least around 500 marks to be on the safer side in your neet  examination

Thank you
