DD1 is taking grade 3 next Tuesday - she's 11 now and did grade 1 two years ago. She was a bit nervous but took it in her stride. She likes studying for the exams; after grade 2 her teacher suggested a break from exam work but DD said no, she'd like to crack on. I might suggest a break after this one though, as she's got secondary school to contend with next term.
She hates performing solo in public, but loves playing in orchestras (one music service and one community folk at the moment). I worried that playing before the intense and indvidual scrutiny of an examiner would freak her out, but oddly enough she doesn't mind that nearly as much as she would playing in front of her classmates.
My friends' daughters have mock exams with their teachers to enable them to skip grades, which works fine for them. I think children who are whizzing through the grades also tend to skip some. DD finds them motivating at the moment... Not sure if DD2 (novice cellist) will be as keen.
The exam lasts about 15 mins - in fact DD has been given a 14 min. slot for grade 3 next week. Don't know what happens if she plays slowly . They play the 3 pieces that they've prepared, some scales, and do some aural exercises, which I think at grade 1 consists of clapping rhythms and singing melodies, but I'm sure a music teacher will be along soon to put me straight if necessary.
Well done to your DD for getting so far so quickly, and I hope she enjoys the violin for years to come.
