As cut-off marks vary year to year depending upon number of students appear in exam and the  difficulty level of exam so if you belong to sc category and if you are applying under 85% state quota seats then to be on safer side you should score above 310 marks to secure a seat in government medical colleges.i hope this information helps you.

thank you

Cutoff marks are different for all colleges in Government ownership and based on quotas. Minimum cutoff marks in SC category at all Government medical colleges in Karnataka for MBBS is 295 marks as per last year trends.

However this will vary every year based on exam difficulty and total students appearing
