Hello aspirant, 

Well you haven't mentioned a category and domicile so I'll be providing some basic information. 

According to last year's cutoff you need to score a minimum of 370 to get into a government medical college in Karnataka if you belong to general category and you have a domicile of karnataka which means via state quota counselling. In that case you may have chances. 

If you have a domicile of some other state and you are going to apply via all India quota counselling then I'm sorry to say but you won't be able to get admission since minimum cutoff last year was 540.

Thank you 

Here is the list of colleges in Karnataka where you can get admission. As you didn't mention,  I am thinking you are from general catagory.  So the cut off are for general catagory only. 

1. Raichur Institute of Medical Sciences, Raichur (380) 

2. ESI Post Graduate Institute of Medical Sciences and Research, Bangalore (368) 

3. ESIC Medical College, Gulbarga(374)
