This is a study notebook containing copies of past questions from the Japanese Language Teaching Competency Test, from Reiwa 1 to Reiwa 5 (excluding listening comprehension and descriptive sections). I've marked the correct answers and written explanations for why the incorrect answers are wrong. I've supplemented the answers with explanations from various websites and videos, and I've repeatedly studied using this notebook for these five years. I've marked the questions I got wrong multiple times, so it's not exactly pristine, but it should save you the trouble of researching information from various sources. There are some torn pages, stains, and scribbled notes, but I'm offering it for sale in the hope that someone can make use of it. Please note that this is a personal study notebook, and I am offering it on an "as is" basis, with no claims or returns accepted.
