Thank you for viewing. This is a high-level Every Study for 4th graders, including both Japanese and Math, for one year, along with the answers. It covers the period from April 2024 to March 2025. The math is from Keirinkan, but since it's for a full year, it should be compatible with any textbook. The Summer Study Plus is also included. There are no correction problems. It was used by copying or writing in a notebook. There were a few pencil markings, but they have been erased. I believe it shouldn't interfere with solving the problems. I have checked, but I apologize if I missed anything. There is some soiling on the cover. Please consider this if you are not concerned about minor imperfections. No individual sales, and no returns are accepted to prevent copying.
