Interlochen Arts Academy?

I received a letter from Interlochen a few months back asking me to check out the school. Does this happen very often? My dream is to become a writer (fiction, novels). I REALLY want to go to Interlochen for my junior year (next school year), but I am not sure if I will make it. At my current school, I am one of the best writers in my class and my classmates are already saying I am a shoo-in for valedictorian. I am working very hard on my portfolio, and all I can think about is Interlochen. Is it hard to get in? How competative is it? What is campus life like? Is the transition to boarding school easy? What can I do to help increase my chances of getting accepted? Finally, what types of scholarships are there? Any other tips or advice would be appreciated! Thanks! :)
