@derekthe1adyhamster Ds's college (not Girton) emailed 26th Nov to say he was on the interview list but that they hadn't finalised it yet but were putting those already chosen out of their misery. His actual invitation for interview came through on 28th.
I believe your son is also applying for CompSci like mine. I take it with a pinch of salt but the spreadsheet is lacking in CompSci numbers.
Ds also got his CTMUA results today, not as great as he would have hoped. However looking at past applicants offered interviews who are sitting CompSci A level they range from 5, mainly 7s and a couple of 8s. It is just one aspect of the application though. Everything counts, GCSEs, A levels plus the supercurriculars.
Hopefully he will hear soon and it will be positive. Has he got any offers from any other unis? I think it does help if they do because they feel that at least one uni is interested but obviously as the deadline is January many unis don't offer this early.
