Entrance Exam Question Collection for Kogakkan High School 2021 Edition 2018-2020: 3 years' worth of questions and answer keys for 5 subjects Mark sheet answer sheets are not included. Although it's old, the questions don't overlap with this year's edition, so how about it for those who want to work on a lot of past questions? I erased pencil markings with an eraser, but there may be some overlooked spots. There are a few pages in the answer key with red pen markings. If you don't mind, please consider it.
