This is two years' worth of past papers for the Basic Academic Achievement Test for 3rd-year students at Nihon University Affiliated High School. 2022 and 2024. The 2022 version was also used by my older sister. There were many places where she had written, so I erased them when I used it, but there may be traces left or places I missed. It's also sun-faded, so please refrain from purchasing if you are concerned. Also, I carried it around quite a bit, so some corners are bent. The deterioration is within a range that won't be a problem if you copy the tests, as you'll likely want to solve them repeatedly. Please purchase only if you understand these points.
