Sorry - pressed post to soon is there an internet word for esprit d'escalier?
The top half of universities in the UK system are excellent: in some more generalist area, wherever you go in the top 20 institutions for your subject, you'll get a good learning experience.
In my subject, I talk to likely applicants at Open Days, and once I know what they're really interested in pursuing within my discipline, if they have a particular interest they want to follow through - then I can suggest a number of places to look at (I don't only push my own institution at Open Day, if there's somewhere else they might look at - I try to give good advice, not sell!)
But I also know, that of the top 10 or so places for my subject (my place tends to be in the top 3 or so) a student will have a fantastic time, and get a good education.
So - with her projected A Levels, and choosing within the institutions which ask for those grades - wherever your daughter goes Gnome she will likely receive an excellent education. Future employment is as much about what else she puts into a whole picture of her education, as only thinking about the "status" of the place at which she studies - for example, taking up employability offers, such as placements, internships, meetings with employers coming to campus. In my department, we have something like tat happening every fortnight & offer fantastic opportunities to students to engage with likely future employers.
So it's also in her hands once she gets wherever she's going!
It's great that we have such a wonderful HE system in this country - it's one of our strongest exports - and does a really good job with domestic/EU students also. In contrast to what a lot of politicians are trying to get you to believe at the moment.
