JUDGEMENT!!!!!
No, one of my close friends in St Andrews was from Essex and was lovely (and quite posh!!!). It was a trek for her too. I can imagine that would make it harder.
I think also, Physics was so intense and time-consuming that maybe it helped ward the stir-craziness, I don't know. How involved is IR? I got the impression it was really difficult??? I would have thought it would be good for employability. I've not even USED my degree for anything yet. I probably should. (I keep forgetting I actually have it tbh... mess... it's printed on like tissue paper unless you take out a mortgage to pay for it to be printed on some kind of royal SCROLL thing hahah. I did not...)
