Hi! My DD has been playing the piano for 2 years now, but her piano teacher does go on holiday quite often. She has recently done her Grade 4 exam, and now is beginning to work on her Grade 5. I'm a bit worried seeing as I found out that most of my friends' children take between 3-5 years to reach Grade 5 on the piano. So is my daughter currently fine, or is she progressing too fast on the piano? Thanks in advance!
