Hey Sujata, You should specify the college in which you are talking about. For any government college you need a minimum of 550 marks in NEET 2019 in the Northern Region and it will be 450 marks in the Southern Region. 

 I would personally suggest you to use the NEET Predictor and explore various colleges according to your category and home state quota and choose the best one for you as this college will be your future lifeline.
