I bought this for my child who plays cello. Her comments are that it appeared to be more for piano. What it consists of is a book for piano and a pull out sheets for cello. The pull out sheets have no cover and the paper the music is printed on is not high quality. There are 10 pieces for each cello and the same for piano. My daughter that plays the cello enjoys the pieces (hence the 4) and considered it at about grade 5. My other daughter who plays piano agrees that it is about grade 5 and also enjoys the music. So all in all not so bad but why not print the pull out on high quality paper?
