Yeah I do find it a bit weird how much people talk about Russell Group for example because all it is is a group of universities, that aren't necessarily the best but the name has got a bit of prestige. Where you went to uni will have very little bearing on your future job prospects to be honest. It's better for your CV to get a 1st at a lower ranking uni than a 2.1 or 2.2 from a higher ranking uni. Having a year of working experience will set you ahead of your peers when you graduate too
