I support everything @blossom posted which emphasizes why the OP’s primary goal needs to be military service if he plans to apply to any of the academies. The OP may have a burning desire to serve, but that doesn’t seem to be the primary goal from the initial post. Service academies are not backups or alternatives to civilian colleges. They are a whole 'nother animal with a unique application process. Rather than rehash my typical responses, I’ll refer the OP to this thread starting from my first comment there. He should read through the rest of that conversation for other pertinent information about making the decision to serve.
Of all the things the OP posts, this is the most relevant for applying to a service academy. Make sure you earn the rank as it will set you apart more than your academics.
