27% seats are reserved for OBC Category https://medicine.careers360.com/articles/neet-reservation-criteria

1)For getting admission is such colleges through ALL India quota yor aim should be more that 600+ marks.

2)For home state quota, you need to score almost 520+ marks.The more the marks the better.
