A set of explanation and workbook for i-Work for junior high school second graders. This is a set of math, English, science, and Japanese. I purchased it at a cram school. There were some writings here and there, but I erased them with an eraser. I apologize if I missed any. One corner of the math book is torn. There are also signs of the corners being folded. Overall, I think it's in good condition. I think you can still use it for test preparation, etc. Please understand that this is a used item. - Title: i-Work for 2nd Grade Junior High - Number of books: 12 books in total - Contents: Explanation and workbook - Theme: For 2nd grade junior high school students Thank you for looking.
