Not correct at all quest1on. I was staggered that St Paul's had twenty one advisors compared to two at my own DCs' school but absolutely nowhere did I complain. I have nothing to complain about! The two advisors at our school work flat out but do an excellent job; the same Ho6 has overseen all my DCs' applications and I've nothing but praise for him, and for how hard he works. My point, if you re-read, is that twenty one is vastly excessive, not that my own DC have been in any way compromised by not having twenty one advisors at their disposal.
(If you can point me to anywhere where I said anything about my own DC being disadvantaged by the lack of a ridiculous number of advisors, be my guest).
As far as 'letting individual students and families decide for themselves what are mitigating circumstances', well obviously they can chuck in any amount of stuff, but the unis will decided what is and what isn't valid. I doubt tutors will take a vastly more lenient approach than I do, to be honest, given some of the comments I've heard first and second hand. 'Mitigate' at your peril at the more academically pressured unis.
