With a combination of part time work, overdraft, credit card and/or loans you should be able to manage it. It all depends on how much you can earn whilst working part time, and how much your living costs are. I've got £4000 savings and will be workign part time and I'm still going to have to dip into my overdraft and credit cards - but then, I am studying in London (pretty expensive) and have no funding so far.
It is achievable, so Good luck!
