Tilak, you haven't mentioned your Category. IP Quota seats in ESIC Colleges are filled through Mop Up round at All India Counselling. In 2019 under All India Quota, an All India Rank of 124514 secured 404 marks and secured a seat in ESI Faridabad under SC Category. This is 2019 data and cut offs change every year. Cut offs change 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. There are a total of 317 seats available under ESIC quota and these also follow the Constitutional reservations. So if you belong to General Category, you will need atleast 550 and more and if you belong to Reserved Categories, you will need atleast 500. This is a rough idea.
