Hello,
No there's not any disadvantage for private candidates who want to take admission in colleges.Being a private candidate doesn't mean that you will not get admission.You and the other students will be treated as same at counselling or admission time.
So you don't need to worry about this and just prepare for entrance exams.
Good luck.
