I am a Sophomore in High School and I am highly interested in the service academies, particularly West Point. I am currently enrolled in all Honors and some AP classes, I have straight A's, a 4.65 GPA, lots of leadership experience(through Civil Air Patrol), and I play sports(Football, Golf). The problem I am having, however, is that I am really not enjoying the high school experience. In fact, I can't wait to get out(but I'm only a Sophomore). I am considering graduating next year, however my main goal is to get into a service academy. Would graduating Junior year lower my chances of acceptance?
At face value, it technically would not lower your chances of admission. You obviously have to meet the age requirement and such, but you said that wouldn't be a problem. The only thing that would harm you would be the fact that you'd simply have one less year to get everything done. Junior year is the biggie for beefing up your resume, getting your DODMERB done, applying for nominations, and applying for colleges. If youre interested in the service academies, this normally would start by the winter of your junior year (at the earliest) and then into the fall of your senior year (where I am now

). But you'd have one less year. Leadership positions are usually give to seniors and juniors, so you'd miss out on the extra there, which would lose you some points. Team captain of your sports and varsity lettering is also an issue. You'd also not be able to apply to SLE because it would happen in the summer after you finish junior year.
Long story short, West Point has a strict image for what you're supposed to be doing as far as your timetable. While it wouldn't technically hurt your chances, graduating early throws a monkey wrench into West Point's timetable, making it a lot harder to get things done the way they envision it. Kudos for the ability to graduate early, that's obviously an achievement. But as far as West Point goes, I'd still recommend applying in what would be your senior year just because it gives you time, which is crucial to the West Point app, and also gives you the opportunity to build yourself up even more. Every point counts. If you graduate early, and you'd be able to go to community college for two years, that might be a big plus. You'd be applying a year later to West Point (but a lot of people do this), but you'd have experience that most high schoolers wouldn't, which would set your app different from the huge pool. You'd also have the opportunity to do ROTC for a bit and then apply for a ROTC nomination which would make getting in a lot easier because you won't have to compete with the high schoolers in your district.
It's all up to you, of course, but you gotta put things in perspective as far as getting yourself ready for admission.
