Honestly your gpa and ec’s sound on par with many sophomores. It sounds similar to my kids. One thing to keep in mind is colleges don’t simply view leadership as a school club title. EC’s can be 100% outside of school and titles are not needed to show leadership. For example years ago I was talking to some admissions reps. They all told me even though my oldest daughter didn’t have a single leadership title she had leadership examples. For instance she did registration for a free summer soccer camp and was a volunteer at a learn to skate program (in addition to her own skating).
If you have a local senior center perhaps you can volunteer to help teach people how to download and use apps. Sounds simple but some people who didn’t grow up with cell phones may benefit from that. For business I suggest seeing if your area has a Junior Achievement program - ours had a free summer camp - it wasn’t school based but in a nearby area open to anyone who could get there. Perhaps see if there is a school or local environment program, a community garden you could help out at etc. However be careful not to over commit yourself since quantity isn’t important.
