Most of what I know about CSM can be found online, I ended up going to Oxford Brookes so I don't really know anything new... I'd just go onto their website and research the course, its a BA so it's going to be more reliant on art skills, especially with it being CSM. I'd book an open day if you can get to London, the one I went to was really useful. I don't remember much from it apart from one guy saying you need to know stuff about current architects, not just famous people like Gaudi (although they never asked me about that at my interview so who knows!).
