Well KMC is a highly reputed college , faces a stiff competition from students all over india, cut off scores/minimum marks required to get into kmc change every year depending upon the level of difficulty of neet that year, no of students applying to kmc that year etc, according to previous years analysis a score of 450+ is ideal and a safe bet to get into kmc from sc category/state quota.

Hello student,
Last year, a minimum score of 261 got a seat in the Karwar institute of medical sciences, Karwar in SC category under the state quota. So, a score of something which is not less than 300 would procure you a seat in the government medical colleges and could be regarded as a safe zone. Also, one thing to keep in mind is that scores and ranks vary each year with difficulty level of the question paper and availability of seats. However you can go through the following link to know about the cut off's and ranks for the previous years and calculate your chances of selection
