It’s true what moo said!
Oxford is close to you and bills etc would be additional cost to the 57K......... but to add another ingredient into the mix……. FTE is only 62K with accommodation and 3 meals a day. However going down the OAT route with some of your training done in the USA you will still have to set aside extra cash for living etc.
I’m not recommending one school over the other……. Its up to you to make the decision. There’s lots of info out there take some time and find out what’s best for you (its took me 2 years of deliberation)
But good luck
