I did Andante Amoroso, Nuances and Columbine dances last year and passed with high distinction.
Generally all the pieces in the book are nice. However, I think with the first piece A1 (can't remember title), you would have to be really secure of the notes come the exam, because when played up to speed, it's liable to getting your fingers tangled up in the fast semi-quavers.

The nuances piece is lovely also, but the harmonies and dissonance in the chords take a bit of getting used to.
Colubine dances is just great! Especially the middle page! I didn't give any thought to the yellow beansleaves. Just take one look at it, and you can see why I didn't want to sight read it. However, i'm not saying it's not a nice piece, it's just not my cup of tea.
