Mabuchi Kyōshitsu (Mabuchi Academy) Junior High School Entrance Exams 6th Grade High Level Special Training: Arithmetic No writing. Review Tests 1-27 Tests 1-25 have problems on the front and answers on the back (see image 5). Tests 26, 27, and 28 only have answers, but you can use them by covering the answers, etc. (see image 6). As a bonus, I will include only the answers to the Practical Ability Confirmation Tests, which are the summary tests for High Level Arithmetic (see image 4).
