Fullerton is a Cal State school whereas Berkeley is a University of California school. The UC system's requirements on paper are higher than the CSU schools. You are correct though that some are harder to get into than others. It is very hard to get into UC Berkeley or UCLA, and much easier to get into UC Santa Cruz. Then there are the high quality CSU schools such as Cal Poly - San Luis Obispo (Go Mustangs!) that are harder to get into than the lower tier UC schools.
What's my point? I have no idea, I just felt like talking about how wonderful California is.....or isn't.
On a side note, I am working about an hour north of Palo Alto (where Stanford is) and I started making about half of their median wages. I wonder if most of these jobs are in engineering, because I'm not sure what other entry level jobs would pay $100,000 for a new hire with just a bachelor's, even if it is from Stanford.
