1 The two universities are almost the same. Newcastle is a traditional red brick university, and there are Manda University, Liverpool University, Sheffield University and so on. Durham University is the third oldest university in Britain besides Oxford and Cambridge. It seems to have a history of 500 years, and it is a rare university town that imitates the Oxford-Cambridge college system. As for people without a degree certificate, it's hard to say.
The cost of living in the two places should be similar. Newcastle is a big city in Northeast China, and the cost of living is relatively low. Durham is very close to Newcastle, and it is only ten or twenty minutes' journey by train, especially in small towns.
Of course, there are also many job opportunities in a big city like Newcastle.
