Hello, 

As per your requirement, i would say that as you have got 534 marks in obc category, and you belong from karnataka so it would be 50 50 for you to get a government seat in karnataka  but you may get it even as you have obc caste reservation for you to avail because your state basically has a high cut off as lot of students belong from that state.

Getting a seat in government medical college is depending on many factors like studenrs to seat ratio, cut off, reservation etc. 

The cut off as per your caste would also depend on which state domicile you have as few states havr higher cut off .So it varies from state to state.

You can apply for both state as well as aiq quota seats. But it would be diffcult as your markd are less as compared to the cut off.

As you want a private medical college, so you can easily get chance in your preffered medical college in your state.

Good luck
