I know this might go against the grain of the board, but I don’t think you need to be the leader of any club or organization to get into a “good school.” (I’d be interested in knowing where you are applying, but in my experience the reputations of “what colleges look for” in applicants is largely hokum peddled by college advisors.) I got into many highly selective colleges by volunteering for local science and environmental organizations, and (this is important!) doing work there consistently. It is a unique field that stood out on my application; even though I did not participate in many school events or “leadership positions,” they were probably impressed by my consistency and drive to pursue my genuine passion outside of school. The word “genuine” is important here - don’t look for ECs that you aren’t actually interested in because they’ll just feel like a waste of your time and you probably won’t get any good learning experience (read: essay material) out of them. Finding your specific passion and searching for local opportunities (no matter how small the organization) is probably the best way to go about this.
