Student loan

Well it's finally happened. I'm finally earning enough so that I have to pay back my student loan. I don't have a clue what size my loan is now - I think I borrowed between 12 and 15 k while I was at uni (the minimum amount you can borrow for a three year course anyway).
This month I'm paying back just over £50. Add that to the £20 golf cart damage ("what golf cart damage?" you ask. thats a story for another day...) and I'm already £70 down this month. Ah well, ce la vie.
