I probably couldn't cope without my overdraft. I wouldn't be able to afford bike bits 😉 The way I see it if you use it during the term, then top it back to black during the holidays you're laughing. Free short term loan, Zero interest. It gives you that bit extra to play with, especially if you have nothing at the start.
If you have any savings at the moment, there's a chance that buying a computer, books, supplies (we needed tools, steel toe boots overalls and safety specs, drawing equipment) pots, pans, bedding, clothes etc could significantly dent them! It may not. It depends how much you have and if your parents are willing to contribute.
EDIT: with NatWest, second year was 1400, I'll extend that anyway to whatever the limit is this year. When I opened it the deal was 1 year at 0% interest after graduation.
