Colleges are interested in what a student has done both inside and outside of the classroom. Students should find things that genuinely interest them and dive deep. Commitment to community service as well as extracurricular activities they are passionate about will not only make them more interesting people, but more attractive candidates to college admissions officers.
There are gazillions of volunteer and summer enrichment opportunities available. Listed below are a few.
