I teach Japanese students in Japan. I have used Barron products in the past and normally like them. However, with this particular product there were problems with one of the CDs, which would jump and skip. This might have something to do with the way they are packaged in the book. Also, all the test answer sheets are incorrectly numbered. Since I actually time the student using this book, she lost concentration and time when it was realized that the answer sheet was missing an answer number (105). The test material itself is good, but due the the problems with the CD and answer sheet, I will not recommend this product or possibly any other Barron products to my Japanese students in the future. I will look for other alternatives first.
