Lol. Last year some people who were amazing musicians ended up with all under 35 at my school. One of them was completely shocked, music apparently is evil to score highly in. It's not as easy as people think.. Idk it must be just the course that gets people. Make sure you get all round A+'s
Yeah, my best friend got 26. Pretty much he just didn't practice his recital pieces as much as he should have even though he was good at the instrument.
Usually around 3 in Solo and 3 in Group.
Since they combined the two subjects it should be a little more -- my chances have increased marginally.

Performance-wise: you do not have to be the next Beethoven. Choose pieces which show off your strengths. There's no need to choose hard pieces if you can play an easy piece beautifully.
What if I can play a hard piece beautifully?

I've already chosen my pieces so I have a year to learn them (not that everyone else doesn't...). They're fairly hard, or they seem so, but I feel like they are within my capabilities.
I know I don't have to be a complete freak at playing, but I realise that there are guys who have been playing since sperm, and while I think I have a knack for playing, I'm unsure if I am state-breaking.
Theory-wise: people tend to underestimate how difficult it can be ("oh it's only music it's a cinch" NOPE). Don't neglect it, work at it consistently throughout the year and you'll probably be ahead of most of the cohort. Lots of people doing music don't take it seriously.
I never found theory to be a problem as far as written questions go, maybe because I'm a maths guy. Aural is trickier but I can work on it, with Auralia and such. I think they removed the "analysis of previously unheard works" component, too, which helps.
Incidentally, my cohort consists of 6 people, including me. This might be a saving point; the SAC component of the study score was increased to 30%, so if I can maintain rank 1 (which is do-able) then it might give me an edge.
