In terms of ECs, my first reaction would be for you to think about what would make your high school experience more interesting for you and for your fellow students. Alternately, what would help people in your community?
If there are not activities in your school that are interesting to you, then what activities would be interesting? Would there be other student who are interested in a chess club, or an outing club, or something else? Would there be any good reason to try to save your schools newspaper?
