Hi sanket 

cutt off varies every year on several factors like difficulty of the exam, number of students applying for exam, number of candidates scoring highest marks. So therefore  would like to advice you instead of thinking about the cut off you work hard and get more than 450 marks to be on safer side for getting admission in a good government college or private college in any region of india. Also, the cut off varies for different categories (UR, OBS, SC/ST). Though the min like elig to clear the NEET exam is 50% for General category candidates which is 119 marks . I hope this was helpful for you. Wish you luck.
