The question is, to both @Revengeofthepangolins and @GeorgeSchmeliott - why are you bothered about this?
If your DC are satisfied that Exeter (or wherever) is the best fit for them, then why are you worried about the results of other applicants? The standard will still be high, because the department is excellent. Exeter's humanities departments regularly top all the league tables -Rates of student satisfaction are high. Drama is spectacularly successful at this, as is Theology (they have quite a famous telly don IIRC), and Archaeology.
Exeter is known as a humanities university, and it's a well deserved reputation (I say this through gritted teeth, as the senior managers at my place are always putting us in competition with Exeter).
I seem to recall that in the worldwide rankings - the QS tables - Exeter ranks in the top 200 universities in the world (and there are 10s of 1000s of universities) and English usually ranks in the top 100 departments in the world.
As a PP has said, Clearing is very different now - universities are on the look out for candidates who've done better than their predictions, or who've changed their minds over the 6 months between firming offers and receiving results. (Oh, for a post-qualifications admissions process!) The A Level results required are always a "ball park" figure.
Actually, I'm so curious about this that I've had a look at the BA English at Exeter - they want ABC with an A in English, and excluding General Studies. This is still a pretty high standard!
If you can articulate WHY you are bothered about this apparently "lower" offer level at Clearing, maybe those of us in the field can respond more specifically.
