I am from australia and i have done up to my Grade 8 and am currently studying for a amus i also have come up against songs that i have done in pervious grades that are in my amus and some that look to easy for amus the reason for this is though that by the time you get to your amus you can read the notes on the page and if they take the difficulity away from the notes it leaves you with technique and feeling thats a lot harder to portray and do than just some notes on a page.
