Hi.
I know you are unsure of yourself, but in my opinion comparing yourself to others isn’t the way to handle the anxiety and nerves while waiting to see if you receive an appointment to USAFA.
People who have received LOAs usually have stellar academics, but that doesn’t reflect every candidate. Every single aspect of your application is unique and when admissions is deciding who to send out an appointment to, USAFA looks at everything you put down and takes it into consideration. Seeing what others have won’t change what you have. Seeing what my SAT score isn't going to make yours more valuable. Seeing what my extra-cirrculars are isn't going to make yours less valuable. Seeing my candidate profile isn't going to affect your chances of admission. While it could put it at a state of peace, it could also make you even more anxious. To me, it just isn't worth.
Don’t think “I’m not good enough”. Have the confidence and say “My application is a true reflection of who I am. At the time and moment that I submitted it, I did everything in my ability to make myself a qualified candidate.” I have thought that since I have submitted it. I am an applicant myself and haven't received an appointment or LOA. And some days I do think "how do I compare? What do other people have?". But then I just remind myself of the points that I made.
The peak for self reported appointments I believe is somewhere between February and March. Don't be uneasy if you haven't received any form of communication from USAFA. Most of us haven't.
Hope this helps.
