Hey, 

According to previous year, these are the cut off marks of various government college in Delhi under state quota for OBC Category:

• North Delhi Municipal Corporation Medical College, New Delhi- 511 marks
• Dr Baba Saheb Ambedkar Medical College and Hospital, New Delhi- 515 marks

This year there may be an increase in the cut off marks, so your chances of getting admission in a government medical College is low. You can try for private colleges instead. Check the link below for further information.
