Hi

In neet 2019,   546 marks was the lowest marks that was required for sc category for getting a seat in  Indira Gandhi Medical College, Shimla    under all India 15 % 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 around 550 marks or more to be on the safer side in your neet  examination

Thank you
