you do realise it is simple - the uni rep / grades etc only take you to the interview that is it (maybe not if you screw up the pre interview tests) then it comes down to you.
I would say it doesn't even matter that much about uni - being able to write a good cv is as good a whitlling tool to get rid of people and reduce applicant numbers as uni rep is (to a degree) - when such whittling is required
But ofc it is obs that if you have a good cv, you are likely to go to one of the listed unis... but still, the list is meh - dont pay much attention to it
