You haven't mentioned your Category. Neverthless, KIMS is a Private Medical College which has Government Quota, Management Quota and Private Quota. If you belong to General Category and you want to secure a seat under Government Quota, you should atleast aim for 450-475. If you belong to Reserved Categories, you need to score between 400-450. Now please remember that cut offs change every year and are dependant on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam.
