Hii jai
As cut-off marks vary from year to year depending upon number of students appear in the exam and the difficulty level of the exam so if you belong to obc category and if you are applying under 85% state quota seats then you should score above 500 marks and if you are applying under 15% all India quota seats then you should score 550 marks to secure a seat in government medical College.i hope this information helps you.
Thank you
