proper spelling and punctuation threw out your application could help :-P
sorry... couldn't help myself
anyway, for applying into music, all you really need... is to be pretty darn good at playing music. So... for the next two years, play as much music as you can and try and become the best musician that you can. I only sorta figured out this last year that I for sure wanted to head into music, and as soon as I decided that, I involved myself in absolutly every musical thing possible that I could... 3 school bands, my own band, lotsa jamming with whoever felt like jamming... 2 lessons a week for the 3-4 months before university auditions. Just get out there and play whenever you can, and when you have free time and you're not out playing, work on learning more stuff in music, on building up your chops. Shit, even when i'm at work (im a grocery store cashier) im busy figuring out new chord voicings and shapes (for guitar) between customers.
Nothing you say will mean anything, if you can't back it up with some proper playing. And if your playing is good enough, anything you say probably won't matter, because they'll be thinking about how good their institution will sound with you in it... as long as you still show some maturity and work ethic and what not (so keep them grades up...)
