I’m also a native Californian and never heard of this school. But it does exist and it’s not some correspondence online school. In fact.....it looks quite reputable. Weird we never heard of it:
I had the same experience.
I noticed this on their website:
"University housing is conveniently located in a safe neighborhood of the city of Alameda."
Very sensible, or at least it used to be sensible when I lived in Alameda a long time ago. Parking in Oakland was dangerous even back then.
