How could I improve my application?

Wje9164be, I am currently living in an area that is not known to be all that competitive, although I know it it still extremely difficult to get an appointment. And by your last sentence, “Also, build a strongapication for a range of selective colleges. Don’t bank on getting into the academy” is this specifically saying that my application is not on par with an acceptance, or are you generally saying it is hard to get into so do not bank on getting an appointment?
