I am going to throw a little background at you. forgive me if you know this. Your numbers are good enough (assuming your ACT/SAT will match up)–you meet the minimums. That could be enough. or not. I will explain…
getting admitted is a 2 track process. You need to earn a nomination from your congressman, senators, or even the VPOTUS. You can get one from any or all–you just need one but you should apply to all. The other track is you need to be accepted by an academy. You need both of these things. They have separate processes but both are required for an appointment to academy.
so first track, the nomination. each congressman and senator can have 5 nominees atyending each academy at any one time. So, for example, your congressman could have 5 openings or zero depending on how many noms he has handed out in the past few years. same for your senators.
For each opening a congressman or senator has he can nominate up to 10 people to fill that opening.
Now your congressman/senator (c/s) has a choice. He can send in 10 names for each opening and the Academy chooses one to fill the c/s’s quota and the other 9 become alternates. So you would need to be the best in your district/state (depending if it is c or s nominating). If you become an alternate then you are competing nationally. Not every c/s will have a qualified nominee, or not every c/s will choose to have every one of their slots filled (say they have 3 openings (currently 2 freshman already there), they may choose to only nom 2 so they have one for next year). They Academy will use the alternate pool to fill out their class (usually bring in 1500 a year expecting 30% attrition over 4 years to graduate approx 1000–they can only have 4000 there at any given time).
The other choice a c/s has is to designate one of those 10 the primary nominee. If that person meets the minimums. they are in. The academy must appoint them. the other 9 become alternates. in that case you are competing against your district or state.
Track 2. getting accepted. while you are competing thru the nomination and doing whatever interviews/essays/etc your c/s wants, you are also sending in grades/scores/pt tests/physicals/etc to be accepted by the academy. It is possible to be nominated but not be accepted. Again, if you meet the mins and get a primary nom a non-accept will be changed. But, if you are an alternate nom and are not accepted you will not be appointed. So back to the competing nationally.
so keep working on all fronts. leadership is a good ting to have. good test scores–recommend taking them now, even as a soph to get a practice round in before you start taking them for real. you look well rounded which is good. start finding out now what your c/s nom process is. It starts way earlier than regular college, and it is possible to miss an early deadline which cam kill ya before you start. find out who the local USAFA/USNA liason officers are so you can start meeting with them. They will be a tremendous help to you navigating this process—especially if your HS hasn’t sent a lot of kids to the academies and the counselors are not familiar with the process.
