They say "fees" in the article. As I remember it, they don't use the term "tuition" for in state students, it's called registration fees. The thinking is something like in state students don't pay tuition at a public university funded by the taxpayers. There's usually other fees i.e. assessments for student centers etc. that vary from campus to campus.
just a point of info, community colleges charge about $15-19 per unit in Calif.
after reading that article, the pragmatic parent in me had to wonder about a 19 yr old majoring in "cultural studies" completely on student loans.
