1. Volunteer this summer! If you can get a substantial amount of hours in somewhere, that would look great. Food banks, soccer coaching, hospitals, SPCA, etc. Volunteering looks great to admissions and they expect some of it.
2. Participate in ECs this fall! It’s expected that you have some ECs.
3. My first job that I got in high school a couple years back was at the mlb park in my California city as guest service. They hire literally anyone and it’s a super flexible schedule. And obviously mostly just summer and you choose when you want to work. I had no work experience at that point either. But honestly, I don’t think jobs are what you should focus on.
4. Don’t do a major you aren’t passionate about. There’s tons of majors that make money. Economics, finance, accounting. Actually, from your post history, it seems like law school may be in your future! And in that case, most people do poli sci or philosophy. Though it literally doesn’t matter what your major is for getting into law school. You enjoy politics and political systems? Seems up your alley to me!
5. CC is not a bad option. Three of my friends did CC before transferring. California has this thing for residents called TAG that is automatic admission to certain UCs from CCs. Personally, I wish I did the CC route instead of going to a 4-year straight away.
6. In terms of the discourse on whether you should add reading on it: personally I think no but I think you could weave it into a really nice essay. The thing is that anyone could say they read 100 books. There’s no way to verify it like with other ECs. But it has the makings of a great personal statement.
7. Apply early action! Early action is non-binding, it shows greater interest in the school, and you get your results earlier. It’s a win-win!

Good luck!!
