My Son scored 152 and daughter scored 312 marks in neet..they are twins..nd are kashmiri migrants..Will they get any private./govt. College

Well it seems as if your son can not have a good private college seat as the score is pretty low but your daughter can get a seat with moderate possibility because her score is okay as per the requirement. Just attend the counseling to know more by the end.

AS I see your marks in NEET UG 2019 you have very less chances of get Seat in Deemed Or Private Universities Colleges.
Cutoff for this year for getting any private or deemed Colleges you have to score around 450 under AIQ & 430 under state qouta for Open Category.
You have even less chances to get any seat if you belong to any category under your state.
There are only 60k seats in India. In which 15% seats are under AIQ Qouta.
FOR getting seat in AIQ is Very Difficult if you are from state which have low no. Of College
You can Try for Paid management Seat in top Deemed Universities.
