Published 2025 2026 Academic Year Practice Problems: Nokai Center Advanced Junior High School Summer Course Textbook for 6th Grade Japanese, Math, Science, and Social Studies This is a science practice problem set from Nokai Center, a major cram school for junior high school entrance exams. This is the material distributed to 6th graders for the 2026 academic year entrance exams. I believe that by thoroughly working through this practice problem set, you will cover the entire scope of elementary school learning. Since the textbooks alone cost tens of thousands of yen, I think this is a great deal. Recommended for those attending a different cram school and looking for practice problem sets, or for those who want to write in a textbook again for review. It also includes key learning points. There are some lines and entries made with pens, etc. (especially in the beginning). Your name is also written, but I will black it out with a marker. Please refrain from purchasing if you are concerned about this. I studied diligently with this textbook and successfully passed my first-choice public junior high school. I think it's also a good omen! It is relatively clean. I will apply tape to the name section before shipping. Thank you for your understanding that this is a used item. Thank you for looking.
