Harsha, no one can give the exact marks and rank for a seat in a particular College. This is because Cut offs are not fixed but they keep changing 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. Last year approximately, while 13 lakh Candidates registered for NEET 2019, approximately 11 lakh Candidates appeared for NEET. This year 15.94 lakh Candidates registered for NEET and we do not know how many Candidates will appear for the exam. And cut off is also determined by the top NEET score and how many qualify in NEET. We cannot predict the exact top NEET score because we do not which student will utilise the time for preparing for NEET and score good and which Student will wayne away time. We cannot  as well predict how many will qualify in the exam. This is important because if the no.of Candidates qualified are more, then the cut off will increase and vice versa. This data can only be gathered after the exam has been done with and the results have been announced. And then due to Corona, Candidates might not select far off Colleges and opt for Colleges nearby. That means Candidates closer to Kurnool might opt for KMC and there might be thousands of such Candidates who belong to EWS Category just like you. It is difficult to gather that data as well without the exam being held because not every Candidate who registers for the exam, appears for it. So to give you exact marks and rank is not possible. If you belong to SVU area, then you will need atleast 625 and more. Again this is not the exact marks range and this is just an analysis based on previous years data.
