I am doing Music 2 next year.. but after looking at all this info.. I reckon I'll change to Music 1. There's no way I'm going to do well if I compete with AmuS and LMuS people
Being good at Music 1 is better than being bad/average at Music 2 right? Even though the scaling is A LOT different?
If you can read sheet music quite fluently, apparently music 2 should be much better to you. I was enlightened by my teacher as to how music 2 receives a score to look at for aural, while music 1 relies purely on listening. Also, although there ARE marks dedicated for technical skill in the marking guidelines, you aren't severely disadvantaged against AMus/LMus people in terms of performance. It's more to do with how you play your pieces rather than how hard it is. That being said, if you really weren't cut out for music 2, I'm sure your school teacher would have suggested you to drop themselves.
You've also got a year to work on your composition (just handed mine in a few days ago, so you've got pretty much exactly a year), and aural just takes practice.
I don't think you'll be severely disadvantaged for staying in music 2 unless you really are subpar.
