hey student 

sorry to say you might not get government college in haryana if you are scoring 321 marks in neet 2019. i can say this on the basis of previous year cut off in haryana which was 486-547 marks for unreserved category for states quota seats in 2018. results are not out yet so we cannot expect cut off clearly we can just predict on the basis of previous year cut off. for more information related to cut off in haryana you can visit following link https://medicine.careers360.com/articles/neet-cutoff-haryana 

thankyou. goodluck.
