This is a poster (A3 size x 4 sheets) containing the knowledge necessary for elementary school entrance exams. I had it posted in the living room so we could always see it. It's a long year, but knowing the basics will be helpful for cram schools, classrooms, and tests. It was attached with masking tape, and there are marks where the corners peeled off. Please understand that this is a used item. #ElementarySchoolEntranceExam
