hey pinki 

as per previous year the cut off bihar for sc category under all india quota ranges between 429-487 marks in neet. we are not sure if same trend will continue this year or not as cut off changes every year depending on number of candidates, number of seats and difficulty of exam. 

here is a link with all the mbbs colleges of bihar with their previous year cut off. i hope this might help you https://medicine.careers360.com/articles/neet-cutoff-bihar
