DS had a Warwick offer within a week back in October but that was for History Politics rather the PPE. I think the faculties decide at different times. DS was thinking PPE or PPL but really wanted History so changed his mind. It also made writing the Oxford PS easier.
I hope your son gets that Warwick offer soon @ComingInByAnsible. and enjoys his OHDs.
DS really liked Exeter as a campus and uni. Again he got a really quick offer and a grade reduction if firmed. However, as @JustHereWithMyPopcorn says I think he thought it was just too easy. They don't care what they do to us do they? 😂 Both Warwick and Exeter were in clearing for history last year too.
DS is a pain as he didn't like Bristol or Warwick. I would like him to go to the OHD at Warwick but he refuses. Bristol is out - he didn't apply. He didn't like the city, the accommodation or the course. Basically he disliked everything about Bristol.
I hope your DS gets that Imperial interview @JustHereWithMyPopcorn with those mock results he certainly deserves it! I realise the accommodation cost would be prohibitive but he might still choose Bath anyway 
Yes, I am not repeating that exercise @Fabfabfab !
