Hii

This comletely depends on the cutoff score and cutoff keeps on varying every year so this can not be predicted exactly. But you can get an idea from the previous year trends  to know what is a safe score.
I would suggest you to keep a high target and score around 560-600 marks to secure your seat in a govt medical college.
Here is a link with previous year cutoffs.

Thanks!

Hii Prashant
As cut-off marks vary 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 490 marks and if you are applying under 15% all India quota seats then you should score above 540 marks to secure a seat in government medical College in mumbai.i hope this information helps you.
Thank you
