Most of them were only used in class, and there is almost no writing at home. Therefore, there are many blank pages. Especially in math, the repeated practice sections are almost blank. @@@For those who purchase math and Japanese language materials together, I will give you the summer course materials and the Science Workshop (Figure 8, 12 books total) for free. Please understand that these are used items before purchasing. If you have any questions, please feel free to ask.
