This is a science workbook from Nokaicenter, a major cram school for junior high school entrance exams. This is the material distributed to 6th graders for the 2026 entrance exams. If you thoroughly work through this workbook, I believe it covers the entire scope of elementary school learning. Recommended for those who attend a different cram school and are looking for a workbook, or for those who want to write in it again for review. It also includes 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. I studied diligently with this text and successfully passed my first-choice public junior high school. I believe it brings good luck! It is relatively clean. I will cover the name section with tape before shipping. Thank you for your understanding that this is a used item. Thank you for looking.
