Breeztye- you will become best friends with your recruiter, the application is lengthy and you will also have to pass the physical exam at one of the army stations. As far as application advice: I was told they look at previous military service (which i did not have), experience shadowing with a military vet (which i did not have), extensive leadership experience since you will be put immediately in charge of other people after you graduate (which I did have), a high class rank (which I did have), good letters of rec (which I did have), GRE, Undergrade grades ect................ The list goes on but I was told the highest priority went to military experience, leadership and grades.
good luck to you.
