Hey Rajendran ! I consider that your son has appeared for the NEET exam. In that case , his chances of getting admission in private medical colleges depend upon many factors like quota , category and mainly marks. Since you have mentioned none of these factors , it is hard for me to tell whether your son can get a seat in private medical colleges. I can just say that if your son has a score above 300 , then your son have fairly good chances for private medical college.
