Hi

Your profile suggest that your domicile state is Bihar.

You have not mentioned the category you belong to, so I am  assuming  you from general category

It's quite difficult to predict that whether you will get  seat or not as  cut off marks/rank for medical colleges 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 when we go through previous data then it suggests that with 640 marks  you hold  a good chance to get a seat in a Government Medical College

For example,
in neet 2019, 577 marks for general category was the cut off marks to get a seat in Government Medical College under bihar State quota and it was for Government Medical College, Bettiah

You also have chances in following Government Medical College under Bihar State quota:-

*Shri Krishna Medical College and Hospital, Muzaffarpur

*Nalanda Medical College, Patna

*Patna Medical College, Patna

And a few more

Above prediction is on the basis of past year data but  cutoff keeps changing depending upon many factors as mentioned earlier, so to have a clear picture of the college in which you have chances and
