Aichi University of Education Attached Okazaki Junior High School Entrance Exam Preparation Collection. Junior High School Entrance Exam Pass Level Problem Collection 1 & 2 Set This is published by Juken Senmon Success and was purchased on Amazon in 2024 for 8800 yen. It is still being sold for 8800 yen. The language and math sections have a 60-minute time limit, and the science and social studies sections have a 30-minute time limit. I went through it once, and it seems similar problems appeared on the actual exam. I used copies, so this is in near-new condition and is a beautiful item, but it is still used, so please understand this before purchasing.
