Eiken Grade Pre-2 Edition for 2018: Past 6 Exams - Complete Problem Collection Includes 2 CDs Seimido Publishing Price: 1600 yen Purchased for my child. Used with a plastic cover after purchase. The answer key and explanations have not been separated. It seems a red sheet was included, but it has been lost. (Reason for "Slightly scratched or dirty") I have a few red sheets on hand. If you'd like, I can include one red sheet. Please let me know after purchase if you would like one. Slight creasing on the cover. There are pencil erasure marks on page 28 and pencil writing on page 29. I don't see any writing on other pages. (I apologize if I missed anything) I remember using it briefly a few days before the exam. I think it's a relatively clean book for its publication year. I will remove the plastic cover before shipping.
