This is the textbook I wrote to support the most advanced high school math/CS sequence in the USA.

It's freely available. Link in first reply.

In Math Academy's (former) Eurisko program, which ran from 2020-23, we scaffolded high school students up to doing masters/PhD-level coursework: reproducing academic research papers in artificial intelligence, building everything from scratch in Python.

We currently have all of Eurisko's math prerequisites available on the Math Academy system (which is where Matteo and other Eurisko students learned it).

Eurisko ended in 2023 when I relocated because nobody else in the district had the requisite knowledge to teach it.

But we will eventually have the entire Eurisko curriculum, and more, on the Math Academy system.

Can't think of a better way to close out 2025 than seeing the head of NASA ask my former student @matteopaz06 to apply, with a fighter jet ride as a signing bonus.

Matteo was one of my students in the Eurisko program, which, during its operation from 2020-23, was the most advanced high school math/CS sequence in the USA.

It culminated in high school students doing masters/PhD-level coursework (reproducing academic research papers in artificial intelligence, building everything from scratch in Python)

Matteo joined Eurisko as a 10th grader, during the last year it was offered, and worked hard to complete almost all 2-3 years’ worth of assignments in a single year. (Eurisko ended when I relocated; nobody else in the district had the requisite knowledge to teach it.)

This is exactly the position that we were trying to put students in with the Eurisko program – get them to a point of skill that they can capitalize on some math/coding-related opportunity and turn it into a chain reaction of fortunate events. And it’s been so great to witness some of these chain reactions get underway.
