Hi

Your profile suggests that your domicile state is Telangana

Predicting the marks required to get a seat  is quite difficult but when we go through previous year trends then

In neet 2019 , 505 marks for obc category was the cut off marks/ lowest marks  that got a  seat in GANDHI MEDICAL COLLEGE, SECUNDERABAD under Telangana 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 students  in neet , toughness level of the neet examination, number of seats available etc.

So ,  in your Neet 2021 Examination to be on the safer side, so you should target at least around 50 marks more in comparison of 2019 cut off i. e around 550 marks .

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.
