Don't know much biology

So initially I was going to ask "UCSJ or U Santa Clara" but since I am the stupid, I searched for UC Santa Cruz and wow that looks attractive too. So, compare and contrast, students, considering that I'm probably looking at continuing either my History studies or my Political Science studies, or both. I'm leery of Santa Clara because it's not in the UC system and thus probably more expensive.

EDIT: Except of course that there is no such thing as UCSJ and it's SJSU which is still a public school just not necessarily in the UC system and thus possibly an intermediate class of expensive.
