I have just gone through the whole application process and somehow came out the other side with an appointment, so hopefully I can give you some of the information you're looking for. When I first started applying at this time last year, I was skeptical that I had a chance. The odds look really intimidating, and really the best thing you can do to beat them is to wholeheartedly pursue an appointment. I come from a small high school where we have far fewer AP classes than most, and that really worried me. However, your standardized scores are more important, as well as your unweighted GPA. As for the chance you have, it looks like you are fairly well rounded, but I couldn't say for sure where you stack up. My advice would be to take all the preparation for the SAT that is possible--and STUDY HARD. Look at the averages for the academy and try to meet them if you can, because that is one of the most important parts of your entire application (though not the only part for sure). Try to see how you do against all of their provided information, and that will give you a pretty good understanding of your shot. A lot of your scores (academic and physical) will depend on preparation and hard work this year though--the more you prepare and want it, the better chance you will have. Another thing--humility and service are also important in your interviews/essays.
