My eldest daughter used these, but she no longer needs them, so I'm selling them. They were purchased from Sanaru Yobiko (a cram school). 1. Japanese Language (with answers and explanations) 2. Math (with answers and explanations) 3. Science (with answers and explanations) 4. Social Studies (with answers and explanations) 5. English (with answers and explanations) 6. Answer sheets A total of 6 items. Since they were used, there are scratches, stains, folds, tears, writing, and correction tape marks. There may also be pages that I couldn't completely clean. Please understand. (See images 1-20) Would these be useful for your child? Shipping will be via 60-size package.
