We are not sure at all what has been possible in the past. So I'm hoping that the next conversation with the principal might shed some light. We do hope for some form of exemption so that she can use the time to do her own music practice or theory work, etc. We also thought about a different instrument, but DD already plays two instruments and sings at a pretty high level, and she doesn't want to pick up another instrument just so that she can participate at school...
