This is a set of Eiken (English Proficiency Test) Grade 4 practice questions and a vocabulary book. It is sold as a set. I am not considering selling them separately. I only used them for about a month of studying, so they are relatively clean. However, since my child used them, I have marked them as having some scratches and stains. The CD has never been used. It is in the same condition as when I bought it. There is no writing in them. (I have checked, but I apologize if I have overlooked anything.)
