Which University did you go to and what did you study?
Art Foundation: Wimbledon School of Art
BA Graphic Design: Camberwell, University of the Arts London FIRST CLASS HONORS
I would recommend the graphics course at camberwell especially if you are moving to london for the first time - camberwell has a nice little community vibe and is more tight knit than the more spread out and higher subscribed courses. You must go have a look around the universities you apply to - that's what I did, and camberwell was the best for me.
Course wise - I think camberwell is excellent in some places, but lacks support in others. If you are willing to fill the gaps yourself its an excellent choice, you will have lots of freedom, and won't be spoon fed.
