The first year of University can be about mostly about getting students up to the same academic level - not too academically challenging. That, combined with the novelty of being away from home and (in many cases) that you're living on campus can make it "fun".
The second year is a different matter. Booted off campus, costs mounting, the academic side gets much harder too and it's not "fun" any more. This may be enough to put off less committed students or cause a few mental "wobbles".
So there may be a little more going on here than meets the eye. The reported attitude of the tutors and the fellow students does not ring true - I don't believe it. You need to uncover the real issues before you can address them, because I strongly suspect you're not there yet. It sounds to me like your daughter wants to drop out of her course, probably because the course and and/or life generally has become much tougher this year, or maybe for another reason.
