回复：Have an assessment from a pro

Yes, she plays vionlin about 4 hours every day. She has the passion on music. She stopped piano for a year, now she wants to continue to learn pliano but still concentrate on vionlin. The reason to keep piano is that she uses piano for her composition.
My worry is she uses to much time on her music even she is all A's student so far. But I'm sure her acadmaic is not as good as other kids because she just finishs her assignments every day, not study deeply.
