Pretty broad question lol. Any specifics you wanna ask about? Accommodation, nightlife, teaching, research, societies, sports, facilities, ethnic/social mix, local area, culture etc?
The only thing that really surprised me about Newcastle is just how ****ing far north it is, i didn't really appreciate how far away it is from the rest of England until i travelled there for an open day. It's pretty much as far south to Leeds as it is north to Edinburgh.
