I'm selling this because I bought it about two years ago and no longer use it. I solved the problems on separate paper, so the worksheets and manuscript paper are unused, and there are no markings. Individual sales are also possible. If you have essays or interviews for high school entrance exams, please consider taking a look. I hope this reference book can help those who have high school entrance exams coming up. #HighSchoolEntranceExam #Obunsha #Interview #Essay
