I have seen varying, even conflicting, information on this site about how much the 'prestige' of your undergraduate university affects your application with some posters saying it should have no effect at all and others saying if you go to a 'lower tier' university your application would have to be of a higher caliber. Firstly, does anyone else have any further insight on this? Secondly I was wondering how my university would be considered. I go to Sussex which sometimes gets a bad rep on this website 'for not being Russell group' but my understanding is it has a pretty good reputation amongst academics (obviously not seen in the league of Oxbridge, UCL, LSE etc. but along the lines of Sheffield, Newcastle, Liverpool, Birmingham, Nottingham, Glasgow etc.) and my department has consistently been ranked top 5 in the UK for 'research influence'. I would expect an applicant from Oxbridge to be treated more leniently than me but, other than that, how, if at all, do you think my application will be affected by my Sussex BA?
