Go to each college’s web site and search for net price calculator. Use it to get an estimate of financial aid and net price for you.
Generally, UCs have pretty good in-state financial aid, although there will be a student contribution of $8,000 to $10,000 per year (typically $5,500 federal direct loan plus some work earnings). CSUs that you can commute to may be cheaper than UCs. But check the net price calculators.
