For the 2026 entrance exams. This is a SAPIX Golden Week text. Textbooks and answer keys/explanations are included. There are writings in the books. For Japanese and Science, the answer sheets are separate, so there are not many direct answers written. Instead, there are many instances of underlining, advice from teachers, and calculations needed to arrive at the answers. Japanese: 6 books Science/Social Studies: 3 books. Pages may be creased or have stains. (I have not inspected each page individually.) Also, as these were used by a child, please refrain from purchasing if you are concerned about minor details. I plan to list SAPIX textbooks gradually as I have time. Please inquire if there are any specific books you are interested in. I have all books except for some from 5th and 6th grade.
