Do not worry about this, you have plenty. Leadership isn’t just about having the title of “captain” or “president”. One of my kids did not have any positions like that, but was able to address this when asked by talking about being a leader by example – she was the top performer in a team academic activity for her team and led them to a couple of very successful seasons (appearances at Nationals), she recruited a lot of people to join the team, and she was a kid who practiced as hard as she played in competition. She was also confident, but not cocky, in taking a leadership role in classroom discussions, which I suspect her teachers called out in her recommendations. She did very, very well in admissions (accepted everyplace she applied, including some top schools). Also, colleges don’t expect you to be tippy top in every single activity. They want some commitment and passion to your top activities, but they also like a student who goes off the beaten path and takes some risks, too. Don’t stress out about this at all, you are fine.
