hello dear student,

the cut off for neet of various government colleges for various courses changes every year and depends on the difficulty level of exams  as well number of students appearing the exam. The cut off also depends on the category you  belongs to. If you are from  any reserved category (SC,ST,OBC) then there are high chances that you'll  get seat in BHMS in government college but if you're  from an unreserved category, then there are less chances with 300 marks in neet.

hope this will help you
