And the rankings can show the opposite of how people actual view the unis. Where I am we have a Russell Group uni and an ex-poly. I went to the Russell Group uni and did computer science, solely because it is a Russell Group uni. In reality, everyone in the local market knows that the ex-poly's computer science course prepares you better for industry.
On the whole though, no one really cares. I can barely remember what I got for my A levels, I can't even remember how many GCSEs I did.
It really doesn't matter in my experience.
