I wonder if there might be scope for some form of "early decision" process. That is you could nominate one University as your early decision. If offered a place you are expected to take it.
This could make it easier all round. DS might have done this with his second choice. Once the dust was settled Universities would have a better understanding of demand and be able to make more focussed offers.
I get the sense that the massively increased demand, especially for maths based courses, plus Gove's reforms have left some University departments struggling to get a clear picture, needing to balance budgets and worried that some of the problems of last year, where popular courses went to clearing, might reemerge.
Some odd approaches are starting to emerge. Bristol economics, who had a reputation for being very late seem to have made a lot of very achievable and contextualised offers early in the cycle, with rumours that they are set to expand their department if they manage to attract a large number of good candidates. . UCL seems to be asking people to turn up to special open days in order, effectively, to collect offers. (I wonder if that is in part to filter out those who have Cambridge/LSE offers already, and those who are mainly focussed on their home country University system but who have also applied to the UK.)
LSE is sending out an interesting sequence of emails saying they are processing the offer and will give further information in two weeks, then seven weeks, and then an encouraging one saying you are one of the strongest in the cohort and you will know in 4 weeks, and an ooops, add in two weeks for Christmas. There is quite a lot on Student Room about the inability to count nor keep deadlines. Warwick simply have a bald statement on Student Room that they will let everyone know by May. Birmingham's approach using unconditional offers is presumably being watched closely.
As education becomes more international, the UK's tertiary education sector has some valuable built in advantages of other institutions in Europe, including English language, a number of world ranking institutions and a reasonably effective approach to undergraduate teaching. Making the most of the current demand and ensuring that students find the right places and that course find the right students in an efficient manner is important.
Sorry, gone a bit ranty. It is a bit odd that it seems to be economics departments that seem to be struggling so much to sort out supply and demand, whereas engineering places seem to have been processed much more quickly.
