Hi

You have not mentioned the category you belong to so I am  assuming  you from general category if you belong to any other category then do let me know in comment .

In neet 2019, 461 marks was the lowest marks that was required for general  category for getting a government quota seat and it was for Vedantaa Institute of Medical Science Vedantaa Hospital and Research Center, Palghar   under maharashtra  state quota . You can check the same at

But 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.

So , you should try to get at least  500-550 marks or more to be on the safer side

Thankyou
