I remember when I was a child, the examination books seemed to relate to one year so if you took the exam in 1985, you chose pieces from the 1985 book. I just looked online for the modern equivalent and saw that there are books for 2013/2014 and 2015/2016. Are the pieces now valid for 2 years now? Also, how long does a child prepare a grade 1 piece for roughly before taking the exam? I cannot remember at all. (DC aged 8 if it makes any difference). I failed a piano exam and was then terrified of them and continued to play the piano without doing exams!
