I wrote according to my ninth grade, black and white, printed at 200 1, but I took the exam in 2008 and my teacher asked me to buy it.
The old edition is divided into several sets, which is very thin. In 2005, I got CET-6, no problem. I don't know if I can do it now.
If you still can't buy it, I suggest you go to the piano city to buy it. Generally, textbooks are attached, so I have more experience in shopping ~ ~
