Nice one Mark, well done mate!!!
I know a couple of guys who've done the MCC in Oxford, they thoroughly recommended it, however they didn't have much luck with the old discount malarky.
However, I would recommend you shop around a bit, cheaper MCCs are out there, and some people regard it as simply a tick in the box, there's plenty of stuff in here about it, so have a search in the forums and see what's available.
All the best and see you soon.
