Thank you for viewing. --- Yotsuya Otsuka Pre-Study Series Exercise Workbook Japanese Language Arts Year 4, Volume 1 (Upper) Exercise Workbook Japanese Language Arts Year 4, Volume 2 (Lower) --- No writing on the problem statements Answers and explanations included Answer sheets included I purchased both volumes for home study before entering the cram school. I solved up to the 6th lesson of the Upper volume and then entered the cram school, so I didn't use the rest and kept them at home. Although there are many difficult problems for parents to teach, the texts used are good, and it was helpful just to read and understand them with my child. I am listing them so that someone else can use them. During inspection, I wrote the answers in a notebook, so there are no writings on the problem sections. However, dates are written on the first 6 lessons of the Upper volume (see photos). Also, since my child used them, there are creases and a feeling of use. There are small scratches on the cover, back cover, and corners from storage. I am a private seller, so I apologize if I missed anything. Please understand that returns and exchanges are not possible. Since these items were used by a child and stored at home, please refrain from purchasing if you are looking for a perfect item. Please consider the photos and purchase. #JuniorHighSchoolEntranceExam #JapaneseLanguageArts
