@warblersrule, the main thing that keeps undergrads from getting in state tuition in CA is not financial independence. It is intent. You have to have clearly documented evidence that you moved to CA at least one year PRIOR to deciding to attend college in CA. Once that glass is broken, it can never be fixed, hence the reason virtually no one can switch their status in CA, even if they do become independent.
