Thank you for viewing. This is the textbook for the Rinkai Seminar's summer course for second-year junior high school students, winter course, and spring course for third-year junior high school students. There are a few pages in the science and social studies sections of the second-year winter course and the third-year spring course with markings and writing in red ballpoint pen. Please be aware of this. The names in the science and social studies sections of the second-year summer course are written in ballpoint pen, so they will be erased before shipping.
