I used this to thoroughly prepare with past exam questions. "Keio Junior High School 10 Years + 3 Years Super Past Exams" for the 2014 academic year. I used it to prepare for past exams even further back than 10 years ago. Highly recommended. It's lucky because I was able to pass the entrance exam. I hope you can use it to pass your exam too. Price: ¥2750 Voice of Education I copied both the questions and answer sheets, so there are no markings inside, and it's in a clean condition.
