Sorry if I sound a bit bitter, but your daughter reminds me a girl I know who plays a few instruments and passed G7-8 at age 10, no distinction though, and couldn't get in Junior Conservatoires. Everybody thought she would pass due to her impressive certificates so it was a big shock for many but more so for the family. Meanwhile someone who'd never taken exam or just passed G5, but distinction, got through it.
The family claimed it was purely because of the lack of preparation and would let her try again with more preparation next time. And I thought, sorry but no preparation would be enough for this girl to get through, even the first stage of the audition.
The girl doesn't know what Junior Conservatoire is and why she is trying to get in. Seriously, they were and still are being too ambitious for their daughter just because she could play the notes of G7 or 8 pieces. But really, high grades mean nothing as you can play G8 pieces with zero musicality. Instead, pure passion, potential and natural musicality mean a lot for the place they wrongly set their eyes on for their high achieving daughter.
Now, I am not saying yours is like this girl, but did remind me about her. By the way she is a lovely girl (sweetly quirky), and I am sure yours too. But, it's so important to see WHY you wants her to try certain schools/challenges and if it really is for her. Your daughter is a high achiever, no doubt, so she can flourish and achieve more than you can dream of as long as she is allowed to be in a right place. And at her young age, it's your job to guide her on to the right paths.
Anyhow, I may be talking total rubbish as I don't really know you and your daughter. Ignore me if it doesn't ring any bell at all.
