LSE sociology ucas extra?

Hey! I just wanted to ask whether LSE have ever put sociology onto ucas extra. I applied to bristol,birmingham,soas,goldsmiths,cambridge and sussex for a variation of sociology/anthropolgy/politics. I got offers from all except cambridge. Now I'm thinking that I want to go to LSE! Is there any chance of there being any space on bsc Sociology? Or should I just go to a university that has already given me an offer?
I'm post a level my grades were AABB and a C at As in biology. My gcse's are 3 A's,4 B's and 3 C's.
