Yotsuya Otsuka Pre-Study Series, 6th Grade, Social Studies Price: 2200 yen There are markings like the image on the "Key Point Check" pages. The first half does not have answer sheets. Answers are provided, so please work on them in a notebook, etc. Answer sheets and copies of the answers are included for the comprehensive review and the second half. This was because I wanted you to correct your mistakes after solving the problems. (I didn't want you to just look up the answers in the separate answer booklet and mark them...) I think it's convenient, so I'll include them as is. I've also cut and pasted the answers so you can easily tackle the questions from Yokkun that appear here and there. Also, I apologize if there are any oversights. Please understand that this is a used item. #JuniorHighSchoolEntranceExam #AdvancedStudy #Workbook #Textbook
