And remember, when you are applying to the academy, you are in 3 categories usually. The first, is does your application meet the minimum standards. Chances are for most people on the forum, the answer is yes. Even without a sport, you meet the minimum qualification. So that took you from approximately 12,000 to about 6,000.
Now, it gets interesting. Out of those 6000 pretty much all of them WILL have nominations. About 5500+ moc nominations and the rest presidential and other military related. This is where the other 2 categories come in. Will you get the 1 appointment from your Mocs slate of 10 nominations, or the 100 appointments from the presidential list? Or will you be competing with the remaining 5500 competing nationally.
In other words, WHO is your competition? I've seen many individuals with super gpa and act and sat scores still not receive an appointment. Either because their competition was better or because academics was all they had. Example.... A guy had a 4.0gpa all ap classes and a 34-35 act. But that's all he had. Little leadership. No sports. Little if any volunteer time or extra curricular activities. And yet, he was still upset that he didn't receive an appointment. I asked him if there were reasons for only doing academics. He didn't have any good reasons other than believing being in the top 1% academically would get him into any top university. I'm telling you right now, it won't. Not even Harvard, Yale, or many others. You need great academics, sports, clubs, leadership, definitely volunteer hours, and other unique qualities that set you apart from everyone else. In case you didn't know, the average entering gpa is 3.86. And that's with IB and AP classes. Also, just about everyone coming in had some athletics. Then all the leadership, volunteer time, and extra activities. It's a lot of competition.
Don't worry about what we say. Don't even worry too much about the nomination. The top kids will get those. You need to worry about your competition. There isn't a checklist you're trying to fill. The applicants for the academies are so far above the minimum standards, that it's totally useless to even look at standards. Best of luck.
