Holy shit! I ran into this growing up in California. Would have been early 1990s. I have long been bitter that I had taken algebra in 8th grade, and starting high school in 9th grade they made me take algebra again because I was told I couldn’t skip ahead that far. I was too young to be in the class. For the record, I’m white snd middle class, so don’t fit that pattern, but I am neuro diverse. Anyhow, everyone has excused it at the time with shit like it must have been a technicality, or that the algebra was more advanced, or something along those lines. Anyhow, it’s nice to be validated sometimes, and this is one of those times so I thought I’d share.
