Cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. When there are too many Candidates and less no.of seats comparatively, the cut offs will be higher. WE cannot predict the exact number but the cut offs are bound to increase by more than 20-25 marks. And in few States like Haaryana, Delhi, Bihar, Odisha, 400 is a very less score. And so these States need atleast 500 for a seat. We cannot point out one factor for the reason of increase in Cut offs.
