Graduate school or ...?

So, after much research, I narrowed down my graduate school choices to 3 schools: UNC, Duke, and NC State. I know people who know me would be like "how could you go to Duke or State after going to UNC?" Well, I know plenty of people who went here for undergrad that are now going to Duke and State for graduate programs. It just so happens that those are the only two schools I found in this area that have MAT programs, instead of M.Ed. programs that are for already licensed teachers. I'd like to stay in this area if at all possible, with all of my friends here and everything I know. I've worked too hard to form connections here to leave it all behind and try to start somewhere new.
I am now just very nervous about applying to graduate school, because I have no idea what my chances are of getting in. Sure, the department websites post their expectations and requirements, but it's really hard to say what they are looking at more in your application. I pray that I will get into one of my choices, preferably UNC, but I will happily accept wherever will accept me.
