My DS is also 10, but as he's a summer baby he'll be going for the U11s!!!
He had 'tense' second lesson with new teacher today! She has said that he needs LOTS more sight-reading practise. Old teacher gave him a mock audition tonight and DS had forgotten everything that he'd just been taught!!! Old teacher would like new teacher to leave the Audition stuff alone as he's been working with DS on it for weeks and new teacher is coming in with her own ideas - not a good idea at the last minute!
Starting to get anxious now! I think that getting into the NCO is more important than it was to us as he will need it to satisfy his orchestral needs if he goes to the local comp!!
