My mom's a teacher at one of these schools, we still have friends sending their kids to them, and I'm still in contact with my HS teachers at that school.

In wealthier areas of the Bay like Saratoga, Cupertino, Campbell, Fremont, Palo Alto, Tri-Valley, Lamorindia, etc the school districts are only paying lip service to common core and still teaching as they were during my time.

Most students take multiple AP classes (and the HSes usually offer 15-20 APs) as well as attend the local CC, UC Berkeley, or Stanford to take additional classes.

The schools that are militantly common core and trying to remove classes are also (frankly) in crap school districts like SFUSD or OUSD where school board elections are dominated by local activists who oftentimes don't even have kids but are using the board as a stepping stone into local politics, and due to their reputations and low pay are unable to hire teachers for more advanced classes anyhow.

There's a reason the kind of house that would go for $1.5M in Sunset would go for $2.5M in the Peninsula or Tri-Valley.
