Hi dear,



I am here to help you with your query. 315 marks are very less for the Unreserved category to get a seat in Mumbai government dental college under both state quota and  All India Quota. To get under state Quota at least you have to score 400+ and 500+ for All India Quota as per 2018 cutoffs. 2018 cutoffs for different Mumbai government dental colleges for UR category is as follows



AIR cutoff marks



Nair Hospital Dental College, Mumbai                                        519



Government Dental College and Hospital, Mumbai                      522



You can try for some other private colleges in other states. But Never lose hopes there will be so many other doors open for you. Go for them.

All the best dear.

Thank you.
