How to I pass my high school interview?

I am going to a very posh private school, because my family is like that and my future is "set" I am going to be in all the honers classes, have friends that are related to the social elite, presidents and many other important people. Meaning that I have given up my punk rock lifestyle and changed to the head prep. The joys. Although I may not like it, that's just how it is and my family has spent too much money on me, for me to just walk off in my own direction. The school I am going to has a tuition of �45,000 per semester so I need to make my parents proud, anyway I have a school interview in a week after passing my test yesterday ( full marks ) with a college level essay. Yes I do show off a lot, what can I say I was raised for andi quote " importance" so after having heard how much is expected of me, you can see why I'm nervous for my interview. Does anybody know what kinds of questions will be asked?
