I am a mum reading my sons STR watched threads. I was until recently a Director in IB, and I can honestly say you guys are all getting too het up on 'which uni'. We, who are recruiting you, never look at league tables, have no idea which uni is better at subject than another, and our knowledge of which unis are best is out of date as we are all much older than you. We are interested in subject/uni and we stick with many of the old fashioned ones because we remember the best ones from when we went to uni. Thus there is Oxbridge, followed by (in no particular order, LSE, Imperial, Kcl, UCL, Bristol,Durham , St Andrews,Warwick). Russell Group means little to us ( unless our kids are applying to uni noone knows who is in RG anyway) and there is ridiculous bias against people from grubby unis up north. Many people have no idea that some unis are falling from their previously lofty perches eg Bristol, as it was just below Oxbridge in my day. We've worked out that Warwick is great now, having been a new uni when we were growing up. We do not study any of these micro diferences. So go to UCL/Kings/ Durham etc and worry not - all of you at these unis stand an excellent chance. I worry for the kids lured into the new top 10 unis, the UEA and Surrey applicants, for these unis may well be fantastic, but do not yet have the prestige.
BTW - for Ronnie. At IBs there are lots of Oxbridge types and failed Oxbridge. They particularly love it when an Oxbridge grad fails and gets binned after the first year. The degree only gets you in the door.
