Thank you for viewing from among many items (*^^*) I purchased this at a cram school in October 2024, but I left the school without using it much, so I'm offering it to someone who can use it. Includes answers and explanations. Japanese: Unused Mathematics: No writing, some folds. Science: No writing, some folds. Civics: Unused History: Unused English: Writing on about 2 pages. (Will erase before shipping) I have checked, but I apologize if I missed anything. Please consider this if you understand. I will try to compress the packaging of the items as much as possible to make it compact for shipping. I may pack it right up to the edge of the bag, so please be careful not to cut the items when opening them upon arrival. Please consider this, as it is stored at home. Also, I do not accept returns or refunds after purchase, so thank you for your understanding.
