Birmingham got back late-ish to one of mine (with an offer) a couple of years ago. Don't panic!
Many of the universities will only have a few applications NOT sent before 15th October (Oxbridge / Medical). 'Normal'
universities also consider (equally) those not
applying to Oxbridge / Medical and they will now start getting those applications coming through. It also depends on the course too. They have their statistics and know how many applications they'll likely get - and when.
Some Unis / departments will wait until the deadline in Jan (or later) before sending any offers! Just because you apply early (Oxbridge) doesn't mean you will hear early - before applicants not applying to Oxbridge - although I'm sure your DD, with her excellent AS grades, and predictions, won't be short of offers.
Be patient. - My Y13 is still debating whether to even apply - let alone get an application in!
