I’m surprised no one seems to have mentioned this yet but the sequences are a good place to start on lesswrong generally (this isn’t high school specific).
Also one piece of advice for high school, which is only distantly connected to rationality: If you want to go to a good university, jump through some hoops while you’re in high school. I spent a lot of time reading textbooks and gave my classes like 15% effort because they seemed trivial and uninteresting, but 25% effort would have probably been enough to get me a 4.0 which would have been useful later.
