Viola NYSSMA questions

<p>So I'm a sophomore now, and have been in my high school orchestra for the past 2 years, and 4 years in middle school and 1 year in elementary. I'm going to be doing chamber orchestra next year, and I've heard people are playing at NYSSMA, and I thought it would be a good idea for next year. Since I don't have a viola teacher, how am I supposed to get a piece, and what else do I have to do?
P.S. If anyone has any level 5 pieces for viola that would be swell!</p>
