Oklahoma colleges are like this. They had some kind of tuition price freeze built into their state constitution so colleges couldn’t let costs get out of control. BUT-- the law didn’t say anything about fees, so schools just jacked those up like crazy.
Problem is that people who get scholarships often get tuition covered, but not fees. When I went to grad school I usually had about $10k per year not paid for. Add that to cost of living and summer classes (which weren’t paid at all) I was spending about $20k per year even though I had a “full ride”.
Just paid off my $150k in student loans this year.
