Hello

In neet 2019, 476 marks was the lowest marks that was required for sc category for getting a government college and it was for   seat  in Lady Hardinge Medical College, New Delhi  under Delhi  state quota

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 marks or more  to be on the safer side

Thankyou
