Dear candidate, 

As for the Maharashtra state there is quota for the 70 percent seats for regional and 30 percent seats for all state. You have some chance if you belongs to regional quota of mumbai.

Here I am providing you with the some name of government medical colleges of mumbai with the last year cutoff marks for the general category aspirants under the 70 percent regional benefit:

• Grant Medical College, Mumbai 544
• HBT Medical College and Dr RN Cooper Municipal Medical College and General Hospital, Mumbai 534
• Topiwala National Medical College, Mumbai 579

If you belongs to 30 percent state quota for mumbai then its really hard to get seat in government medical colleges of mumbai as per your said marks. And if you belongs to any reservation category then you have some advantage of cutoff marks.

For more information on colleges and their cutoff marks for the Maharashtra state, follow the below link:
