I am fortunate to have been in the same position as you. Many people feel that people such as us are spoilt and don't have the determination of people that have had to fund themselves. In most cases I feel that this is rubbish. I have felt a real commitment to my parents not to let them down and work much harder beacause of this than if I had to pay my own way. It is my belief that some of the airline sponsored students are not so committed and make poorer students than us.
Anyway good luck and don't let your parents down.
