PDub is 100% correct. Without counting, there are is probably more than a 100 possible extra curricular activities, sports, leadership activities, volunteering activities, etc... Obviously no one can do them all. And obviously not everyone who applies to the academy has all the same likes and dislikes and interests. It would be pretty crappy to say; "You might not like scouting, civil air patrol, JrRotc, Football, etc..... but if you don't do these specific interests, you can't get into the academy". Or similarly; "If you do this LIST of activities, you're almost guaranteed to get into the academy".
Scouting in general, and eagle scout are very admirable activities. I was in scouting for about 10 years. I loved it. And the leadership you learn in it is definitely a feather in your cap when applying to the academy. But so is CAP; so is JrROTC; so is captain of the Football team; so is class president; so is Head of your FFA chapter; so is going to Boy/Girl's State; and so is a hundred other things. Just like football doesn't garner more points than baseball, soccer, volleyball, track, etc... (One caveat; if you are a nationally ranked athlete being recruited by the academy, that's a different story); but 80+% of all cadets have varsity letters. Doesn't matter which sport.
The academy wants individuals who are leaders, team players, those who help others, excellent academics, and so on. Any activity you do in no more important than any other activity in the same category.
So be proud of your eagle accomplishment. Enjoy the time with your troop and friends. But your scouting and eagle scout will pull just as much weight as the applicant who is the class president, or in CAP, or is a club officer, etc.... And FWIW; only approximately 10-11% of all cadets were in scouting at all. And definitely not all of them were eagle scouts. Best of luck. Mike....
