Hello Shreedarshini,

KPC Medical college is a private medical college. Therefore the cutoff isn't much, you need to qualify NEET with 40th percentile (the cutoff for SC category). Previous year cutoff for the KPC was 347 marks for SC category but cutoff varies from year to year it depends on various facts like the dificulty level of exam, number of candidates, number of seats, previous year cutoff trend etc. So it will be better if you have around 400 marks in NEET 2019 to get assured seat in KPC medical college.

you can also check out the cutoff for the various medical colleges of West Bengal from the link given below -
