Very salient reference to a SciFi classic:

After school math clubs/private tutoring in advanced mathematics (and other STEM subjects) is the obvious countermove by parents. And some punitive response by the California DOE and the fascist Democrats in the state legislature can be expected.
“EQUITY” demands that attempts to again create merit-based distinctions be suppressed and the perpetrators of such inequality be chastised.
In other articles on the subject, the “heterogenous” math classes are reportedly limited to K-10. This implies that advanced classes might again be taught in 11-12. So maybe all is not lost.
