Hello,
If I consider the previous year data .Then you have negligible chances of getting admission in any of the government colleges in karnataka even through state quota . If I talk about previous year data then minimum marks admitted for an st candidate was 335 for Gulbarga Institute of Medical Sciences, Kalaburag. You can either go for some private college or you can opt for some other course. Do remember that The cutoff changes almost every year,so not much can be predicted .cutoff depends on the difficulty level of the paper and the number of students who appeared for the entrance exam.
Just hope for the best
