I'm a junior now and interested in USAFA. I don't do a sport in school because I have no time(I work out on my own time though, so I'm not worried as much about the CFA). I have a 3.5 unweighted, 3.92 weighted from my freshman and sophomore years at a competitive high school. I'm VP of speech and debate, recently part of Civil Air Patrol, NHS, Guitar band, teaching theology at local parish, and Indian club treasurer. I mostly don't have time for a sport because of my EC's and also because I have a year old brother who I have to babysit while my parents are at work. I'm not sure if that is something I can put on my application, since I think it would be more of a house chore rather than a job. Does this really bring my chances down by a lot? Thank you for your help.
