That's kind of what I think but feel free to poke holes. It seems like there are three tiers. There's a closed off top tier of kids who get into top ranked universities. They go to highly ranked schools like selective high schools with high Ivy placement ranks. Those schools have different materials and more opportunities than most. These high schools are geographically mostly on the coasts. It's a totally different culture too where there's this years long effort.

Then there's a middle tier, the majority of people, where they might end up at a university but it's not top rated. Increasingly it's not worth the money and simultaneously it seems like our country has become more credentialist about prestigious jobs. But a degree probably isn't necessary for most careers that don't have gatekeepers so for these people the education doesn't really have a big payoff and their education might get de-emphasized.

Then there's the bottom tier which is self explanatory.

In my experience, the "top tier of kids" is more cultural than school-specific. Even in schools like TJHST there's usually 10–30 students in the school that really care about achieving, while the other 90% don't put in much effort (beyond your typical public schooler). There are a few feeder (public) schools on the coasts, but most of the private schools differentiate by extracurriculars (fencing, rowing, horseback riding) rather than academic excellence.

		Accelerated tracks would produce the top tier, which begin in elementary school - so it's a matter of how much your parents invested in your education before school. Any child can technically enter the accelerated track at any grade. The later they join, the more untaught expectations there are. The other students went over these things already in previous accelerated classes. There's no on-ramp. In the normal track, you don't eventually take calculus in math, learn much about labwork in science, or even learn how to write a research paper until the last year of classes at 18.
