I found out I got accepted as well and I'm definitely going there. I have 3 friends already in the department for graphic design and while the professors can be pretty tough on you, they seem to like it. I also hear the professors make the students very competitive against each other in order to do well, but there's also quite a bit of collaborative group design projects. As long as you're able to take some harsh criticism I think you should be fine.
artsymom: I think Cal Poly is definitely a better choice than ucsb if you want to do graphic design or any more design oriented career since css doesn't seem to have any design concentrations.
