Thank you for viewing. This is a set of weekly test question books and answer keys for 4th graders, conducted in the 2023 academic year. I purchased these in 2024, but I didn't have a chance to use them, and there are no signs of being opened. They have been stored on a bookshelf. ● Price Both volumes (Upper and Lower): Math, Science, Social Studies... ¥1,760 (tax included)
