Hi, 

If we look at the cutoffs of various government colleges for the year 2018,then you do stand a good chance of getting a seat.

Last year Bidar institute of medical sciemces and Raichur institute of medical sciences closed at a score of 283.Gulbarga institute of medical science closed at 279.Karwar institute of medical science closed at 261.

So you do have fair chances. 

However thus analysis is based on last years trends and the cutoffs tend to cary every year. So nothing can be absolutely ascertained. 

I shall provide a link for further info:

All the best
