There is nothing to called PASSING MARKS in NEET Exam. In NEET, it is QUALIFYING MARKS rather which is 50th percentile (approx. 118 marks)
I f you have just qualifying marks then you can apply in any private college but you can not able to get Seat in govt. medical college by these nos.
For a govt. medical college seat, you have to secure at least 530(with all India quota) in NEET. 530 is a safe score but it depends on no. of rounds of counselling conducted by mci. Cut off may come down, but still try to secure above 510.
Cut off marks differ hugely for state quota seats. So it depends to which state you belong.
