I'm a music teacher, although not piano, my own piano development stopped at Grade 5 several decades ago. I do feel able to help and advise, but have one query:
How usual is it for left hand scales to go down then up? My daugher prefers them this way for some reason. It says it's ok in the pieces book, on the scales page, but how often would examiners hear them like this? Often enough not to comment or think it's wrong?
