I'm senior that gonna be graduating in June and I don't know what to do after school :/

I'm planning on taking a gap year to think about my future and I was looking online to see what some people do for a gap year.

I came across this organization that some people do during their gap year.

It's a organization that helps kids in high poverty schools.

It sounds like its fun but I'm wondering if anyone been or know someone that's been in it, that can tell more about what's it about and is it worth it?
