Hi

it's quite difficult to predict the marks required to get a Government medical College in Mumbai or Thane as cut off marks  keeps changing every year depending upon various factors like number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But as per previous year trends being from OBC category you should target at least 575 marks to be on the safer side to get a Government medical College in Mumbai or Thane

For example,

In neet 2019,   546 marks was required for a seat in Rajiv Gandhi Medical College and Chhatrapati Shivaji Maharaj Hospital, Thane and 554 marks for a mbbs seat in Lokmanya Tilak Municipal General Hospital and Lokmanya Tilak Municipal Medical College, Mumbai for obc category under Maharashtra state quota

Thankyou
