For the 2026 academic year entrance exams. These are SS single-subject texts. 15 books in total. 01-12: Social Studies, 12 books 12-14: Science, 3 books Texts and answer keys/explanations are included. SS single-subject is a course for 6th graders in the latter half of the year, where students choose two subjects they find particularly difficult and concentrate on training all units. I chose Social Studies and Math. I switched from Social Studies to Science in the latter half. The Social Studies texts are condensed by geography, history, and civics within each book, making it very easy to review previously learned material and very user-friendly. The 12th book is blank. There are writings in the books. Social Studies The answer sheets for the final confirmation tests are separate, so there are not many answers written directly in the test. Other than that, there are writings, but since the answers can be hidden, I think they can still be used if you intend to. Science I don't think there are many writings. I will also include the knowledge confirmation tests that were given before each class as a bonus. There are writings in these. Pages may be folded, stained, torn, or have notes written on the cover. (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 texts gradually as I have time. Please inquire if there are any specific booklets you are interested in. I have all of them except for some from 5th and 6th grade. I plan to use simple packaging. Thank you for your understanding.
