Eek - this thread is becoming a bit quarrelsome, but I shall stick my oar in anyway.
I was a university lecturer and admissions tutor in a pre-92 university before having children. I dealt with many, many first-year students who were struggling with university life/finding that their course wasn't quite what they'd expected - and so on.
45nanny, if your daughter is still feeling like this, my advice (FWIW) would be for her to talk to her tutor in the first instance. University is very different from school, and it's possible that the expectations haven't been made clear to her regarding time spent on private study and such like. It can initially seem as if you have acres of spare time - but nobody really tells you that that spare time is supposed to be spent in the library/doing private study/creative things/whatever could make the difference between a low 2.2 and a high 2.1 (or, nowadays, even a I). If this spare time is filled, boredom should not be an issue.
The other possibility - and this is also something for your daughter to talk to her tutor about - is that she is right, and the course is a waste of money for her. She will be investing a vast amount of time and money, and she has to be as sure as she can be that it is an investment worth making.
Has your daughter really thought about - and discounted - the more academic options that might be open to her? Sometimes it can be a good idea to get a degree in an old-fashioned subject whilst gaining outside experience in the subject that interests her (in your DD's case, fashion). If you were to quiz journalists, for instance, you'd probably find that most of them did English degrees, not journalism.
I fear this will be seen as critical, but it isn't meant to be. I just think it's worth entertaining the idea that your daughter might need to have a re-think!
