Hello Krishan

You didn't mention the state you belong to dear as cut off marks for getting into medical colleges varies from state to state.

If I tell you about neet 2018, then 559 marks was required for getting admission in government medical college for obc category under state quota for Rajasthan and it was for Government Medical College, Dungarpur.

But cut off marks keeps changing every year depending upon various factors like number of students that appeared in the exam, kind of marks scored by students, toughness level of exam etc.

So , try to get around 560-570 marks at least for getting into government medical college.
Also more the marks you get in neet,  better is the college you get.

I hope that it helps you : )

Thankyou
