For the 2026 academic year entrance exams 6th Grade Saturday Classes Weekly Sapix textbooks. All 36 books. Textbooks and answer keys/explanations are included. (Separate pre-class tests, etc. are not included.) There is writing in the books. Because there are answer sheets on separate paper, there isn't much writing of the answers themselves, but there are many places where advice from the teacher, and the calculations needed to arrive at the answers are written. The "Knowledge Completion" section at the end of the last few pages is filled in. Pages may be folded, stained, or torn, and there may be notes written on the inside of the covers. (I have not inspected each page individually.) Also, these are used by a child, so please refrain from purchasing if you are concerned about minor details. I plan to list Sapix textbooks in my free time. Please inquire if there are any books you are interested in. I have everything except for some of the 5th and 6th grade materials.
