Hello

What is your domicile state and  which category do you belong to?

This is required as cut off marks  depends upon various factors like your domicile state , your category, number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

Nevertheless,  as per previous year trends, you should try to get at least around 550 to 600 marks to be on the safer side in your neet  examination if you want to get a mbbs seat in government medical college

For example,
in neet 2019, 553 marks for general category got into a government medical college i.e Burdwan Medical College, Burdwan  under west bengal state quota

Thank you
