New Junior High School Problem Collection: Confirmation of Important Terms - Science, Year 3 This is a science problem collection for third-year junior high school students, used at Waseda Academy. It was purchased in 2023. The answers were written in a separate notebook, but there are some notes on some pages. In addition, I am also selling many other textbooks and problem collections from the 1st to 3rd years of junior high school, including the New Junior High School Problem Collection and Key Work, so please take a look.
