Does anyone have any advice for scoring 90% and over for the composition and viva voce on the composition? (core Australian music for the last 25 years)
It's very important to start as early as you can so that you get as much feedback as possible from your teacher. Discuss your composition ideas with your teacher to see what they think, and every time you finish composing a section get some feedback - that's the best way for you to know if you're on track or not.
