You application is weak in this regard. Most appointees are (multiple) varsity athletes. As you can see from a recent class profile:
https://westpoint.edu/admissions/class-profile
Of an incoming class of 1210, almost all were varsity athletes and most earned letters:
Varsity Athletics…1200
Letter Winner…1067
Team Captain…808
So, keep at whichever sports you DO play and see if you can earn a letter and/or a leadership spots in at least one of them. Martial arts are not team sports and are not valued the same way. For grades and test scores, you should study the stats in the above link and make sure you at least meet if not exceed those metrics.
As for chances, I will repeat what I tell every applicant who asks (and you would have seen this very response if you read any of the other “chances” posts on the subforum). Due to the vagaries of the nomination process and the rubric the service academies use to determine appointments, it is impossible to chance anyone for a service academy beyond the general advice given here.
Your first step is getting a nomination. USMA does not consider applications without a nomination, so you need to familiarize yourself with this process if you aren’t already by checking the websites of your congressperson and both senators. Once you start the nomination and application process, you will be assigned a Field Force Representative (FFR) who will shepherd you through this process and who will have insight into how competitive your district is and how you stack up against the competition in the year you apply. Getting the nomination is the gating factor; once a candidate has a nomination and is deemed 3Q (qualified academically, physically, and medically), the likelihood of an appointment is close to 50%. How likely YOU are to be 3Q, no one here can tell you. You will also need to dig deep to be able to explain clearly and genuinely to the nomination panels why you want to serve as an officer in our armed forces. Also be prepared to answer your understanding of the consequences of your decision.
Also, you should scour the wealth of applicant information on the USMA website and serviceacademyforums.com (CC for military applicants) where you can learn more about the process and get all your questions answered by current and former military personnel. However, no one there will chance you either for the reasons I gave above. These sources will tell you to do your best academically, up your physical fitness game, and pursue leadership opportunities. You will want to show quality over quantity, stay focused, and put your best application forward. That’s all you or any candidate can do.
You miss 100% of the shots you don’t take. Also, you have until you’re 23 to age out of entering West Point. You have plenty of time.
Good luck to you!
