Hi

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 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 620 marks you hold a  good chance to get a  seat in  Nalanda Medical College, Patna

For example,
In neet 2018, 598 marks for general category got a  seat in Nalanda Medical College, Patna  under Bihar state quota

To get the complete list of colleges in which you have chances, you can go through our college predictor at
