Pretty sure they have to include MCC in the course to get approved as an integrated course. Don't quote me though!
As far as the OAA cost goes, it aint far off £80k surely (although I believe you have actually been on the course ww). 14 months of living costs in Oxford and Goodyear. Surely you will not get much change out of £12k?
Anyways, UK based Integrated are the most expensive. Around 70 to 80 grand all in.
The best place for training is a very individual choice.
