“Achieve Your Potential for Middle School Entrance Exams! Guaranteed Success Project: Secure a Deviation Score of 63!” This is a set of three books: Japanese, Math, and Science. I bought these, but I was so busy with homework from my cram school that I couldn't use them, and the entrance exams were over before I could. I think the content is quite difficult, as it aims for a deviation score of 63. I am offering these in the hope that they will be helpful to those who are about to take middle school entrance exams. As shown in the photos, there is a fold on one page of the math book, and there are only a few notes written in the Japanese book (on page 18). The answer key for the science book looks like it got wet and dried, but I don't think it will affect its use. Science: Includes a red sheet. *I have a cat. Please refrain from purchasing if you have allergies or are concerned about this.
