I'm afraid I don't know anything about that actual course at Birkbeck, but I can say that Birkbeck is a really good university for postgraduate study, with good teaching and research. I wanted to go there to do an MA in a different subject area and despite being a strong candidate (as I was told), I was rejected. I was later told by my tutors that my rejection could have been due to my age (21), as they are used to taking older students with more professional backgrounds. I was a bit put out by this but at the same time I do not have anything against the university and would certainly recommend it to others - I may even apply to do my MPhil/PhD there in due course, I have another Masters place now which I think will be much better for me.
There is an open evening soon (sorry if it has already passed), I went to one back in February and it was really good, go on the website and book a place. Good luck!
