Like someone above said, if you have a career in mind like doctor, lawyer, engineer then it's very useful. However my personal experience is that it's not worth it. I'm going to be £54000 in debt and all I've really learned is that I definitely don't want a career in the field of my degree! I don't enjoy student life in the sense that I'm not all that sociable, not interested in clubbing or partying etc and whilst moving away from home was great (I found I adapted to independent living really well) I didn't really enjoy it until I got a house in second year and felt like I really was being independent (I was in halls during first year and it was HELL).
If I could go back to when I left college then I would choose to take a different root- either an apprenticeship or, as I don't have a career path in mind, just any work. I think experience is so much more important than the crap they 'teach' at uni and it's also where a lot of students (especially those who don't have part time jobs) fall down.
