Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
Hello Sigma Freud,
Seeing as no one else is responding here's my $0.02
I applied and was accepted to CCS but did not end up going. Regarding the application, yes there is a separate one. Most of the information you need to know can be easily found by a quick google. I think they redid their website a couple of years ago around the time I was applying and the process should be clearer now.
I do not think they released any statistics on applicant numbers or acceptance rate but as a rough guide it's about "as hard" to get in as say UC Berkeley.
Also note that the CCS application is subject-specific and it is more competitive for subjects UCSB is strong in (or so I have heard).
