Written exam is less important then the performance, however if you want to get above 40 you have to score an A+ in Coursework, Written Exam and Performance Exam. Music is very competitive, you need to reach top percentiles to obtain a high study score.
Thanks, I see you did it last year, care to share your experiences with it?
I highly underestimated how difficult it actually is. I'm ashamed to say these were my results:
B+, B+, B+.
The hardest part of my year was the theory. I lacked a teacher for the most part of this (instrumental teacher) and I had a lot of work to do in terms of performing. With my mind focused on perfecting my performance, I left my theory in the background. This was possibly the worst decision, because theory is crucial for the exam and coursework, and of course playing (I'm assuming you're a decent player anyway if you're studying Music at 3/4 level), but without a decent mark for theory, your performance mark won't boost your study score.
My advice would be to stay on top of everything and keep a balance. I studied Contemporary Guitar: Solo. Guitar is a very very difficult instrument to perfect in the examination room, you need to show as much versatility as possible.
I see that you're studying horn, and by horn i'm assuming trumpet? I would choose difficult pieces if I were you. Don't perfect easier pieces because the examiners will pick that up straight away and mark you down for simpilcity. You will still get a decent mark, but if you want full marks you need to nail difficult pieces, even if there are a few slip ups in your performance. Again, show as much versatility through your playing, choose different genres, experiment with tone and texture,let your music flow and remain confident.
