As money is very important to you I would think VERY seriously about university before you go through with it. I don't want to put you off furthering your education but I have recently graduated with an £11000 debt and will have to pay this off as well as somehow funding flight training.
Thanks to the good old British government you will probably end up in a similar situation so if you do go to uni make it worthwhile by studying aviation or maths/physics etc. Otherwise you could graduate financially worse than you started off, with a degree that is unlikely to get you any nearer to your ambition.
