Out of state tuition in most places makes state colleges very prohibitive for out of state students.
In state
Course fees are provided in the "class notes" after each subject listing in the Class Schedule. Fees may range from $4 to $500 depending on the course.
Out of state
Nonresidents and foreign students are required to pay out-of-state tuition in addition to the mandatory registration and course fees. Tuition is charged at $372 per unit. General authority of this fee may be found in the California Education Code, Section 89705. The total nonresident tuition paid per term will be determined by the number of units taken. Effective fall 2010 and until further amended, there is no academic year maximum for the amount of nonresident tuition. The annual cap of this fee has been eliminated.
or $1,000+ per class (as most are 3 units). Standard load is 5 classes per semester, or over $13K a year.
Also, be aware, (if you're not already) that California runs two university systems, the California State Universities (San Francisco, Santa Cruz, Sonoma) or the University of California (Berkeley, UCLA). Berkeley requires that you be in the top 1% of your HS class, and, at that, you are not guaranteed admission. Also the above rates are for the Cal State University system, the University of California rates are much higher.
