What are my chances for boarding school? (Reapplying to 9th grade)

I might be a freshmen but I’m not a idiot :upside_down_face:. I know that adding more schools to my list doesn’t guarantee my admission into one of them. Plus I already attend a top public school in MA and its already good educational wise. My public compared to other boarding schools other than the ones I’m applying to are almost none. The only difference is more independence, taking classes you belong in, and better clubs. So in my head its either just go to one of the top boardings or just stay in my top public school. Thanks.
