Im doing education at UWIC (well have a conditional for this September) and thats the same campus as Sport, Cyncoed. I went to an open day recently and the campus looks awesome! I play netball myself and so was interested in the sports facilites and they are impressive. Obviously not sure on how good the sports courses are but the teaching of my course sounds good.
Cardiff itself is an amazing city! I live just over the bridge in Bristol and go over to Cardiff for nights out regularly. Cheap and plenty of places to go. What sort of things did you want to know?
