Sapix Open by School: Waseda Junior High School Question Paper and Answer Explanation, with Bonus This is the question paper and answer explanation for the 2022 November Sapix Open for Waseda Junior High School. As a bonus, I will include A3 size copies of the questions and answer sheets (mainly from 2020-2022, 1st and 2nd sessions, for each subject). These are very convenient for solving problems and submitting them to the cram school. Please refrain from asking questions about the bonus. There are pencil markings. Please understand that this was actually used by a child before purchasing. Please note that the shipping method may be changed after packaging.
