If I had no savings etc I'd be ****ed. I worked from 18-21 to make sure I could afford to go to uni, and its a good thing I didn't just rely on my parents because my mums been made redundant and so wouldn't be able to give me cash anyway.
I get like 5500 loan and something stupid like 165 grant, which barely covers my accommodation. I sold my car at the end of first year for ~4k, so I've got 2k each year to live off without dipping into my proper savings, which is £50/week, top that up with the money I'll earn over summer and it'll be ~£100/week to live on.
