Hi

It is very difficult to predict marks required to get a seat in R.G. KAR MEDICAL COLLEGE, KOLKATA, but when we go through previous year trends then,

In neet 2019 , 462 marks for sc category was the cut off marks that got a  seat in R.G. KAR MEDICAL COLLEGE, KOLKATA  under West Bengal state quota

You can check the same at

But yes,
cut  off   marks / rank   for medical colleges keeps changing every year  depending upon various factors like  number of students that appeared in the neet examination, kind of marks obtained by them in neet , toughness level of the neet examination, number of seats available etc.

So ,  you should target at least around 525 marks  to be on the safer side in your neet 2021 examination .

Now , limited time is left for your neet 2021 examination, so focus on preparation, go through the chapters , practise questions and then revise them, go through mock test papers once you are done with complete syllabus.

Thankyou
