This is a science problem set for advanced junior high schools, offered as a paid course on Sundays at Hamagakuen. There are almost no writings. The name portion has been cut out only for the July/August course. The level is said to be for schools like Kankandoritsu, Hibarigaoka, Kobe Kaisei Girls' School, and Sanda Gakuen. How about using this for self-study for those attending other cram schools, or as a textbook for tutors and private cram schools? Other subject textbooks are also listed.
