Hi

For Karnataka, last year cutoff was on higher side.

It varies every year depending upon number of seats available, exam difficulty and number of candidates. So it's hard to be precise about cutoff. But keeping last year's trend in mind, cutoff maybe as follows-

For All India Quota

SC category- 580-470

For state quota

SC category- 370-350

So yes, you do have a lot of chance to get admission in medical college

Best of luck
