When you live on campus, you live in a dormitory owned by the university. What kind of questions do you have about it?
Is it worth it? Not sure what you mean by that. There is nothing inherently different or special about a college that is not in your own state. Some colleges in your state might be better suited to you and more affordable than some colleges outside your state. Or vice versa. You should go to one that suits your interests and desires and that you can afford.
