LSE & Edinburgh Social Anthropology

Hey, I'm wondering how is those two courses like for people who got in, is the university itself ok and is the course too demanding?
I'm applying this year and now have a application grade of A,A,A and all 8 or 9 for GCSE.
Is that enough to apply for those two courses?
Cuz I have just looked at Unifrog for the typical offers, despite the official website saying that the entry requirement is AAA, Unifrog says that 60% offers are made to student who gets A*A*A, so I'm a bit panicking right now.

So what do you think are the chances for me to get in, and any comments about the courses?
