This is a bit random, but apparently for the Cubs musicianship badge dd1 has to prove she's at a certain level in her chosen instrument. Which would be fine, but it's voice, as she sings in a church choir, so she doesn't do grades, but the RCSM workbooks.
The Cub leader said anything that was an equivalent to a grade would be fine, so I'm trying (and failing, via google) to work out what (very roughly) the equivalent grades would be for the RCSM workbooks. Does anyone know?
