Test preparation for the autumn 2023 fire department and police exams. I have passed the exams for four fire departments so far: one in Kyushu, two in Kanto, and one in Shikoku. I used O-Hara's materials for all of them. I've looked at all the 2023 materials, and the content is almost the same as the materials I used about 10 years ago when I passed the first time. Also, I asked the O-Hara instructor, and they said that the key points and trends for each fire department don't change much. As you can see in the photos, I've written notes, checked key points, and used highlighters in the materials for numerical reasoning, politics, economics, society, Japanese history, geography, etc., and I've also written down points from the actual lectures. I haven't written anything unnecessary, but if you're concerned, please erase it before using the materials. I would appreciate it if you could only purchase if you are not concerned about this. I have also written down many key points from the lectures that you can't learn unless you attend O-Hara. Please make good use of them. The mock exams, science, biology, and materials after the second photo are new and have never been used. Please note that the exam guidebook shown in the photos is no longer available. I have taken the exams for more than 10 fire departments and police departments, but I believe that the materials sold in bookstores are lacking in content, and the chances of passing are low. I know this for sure because I have used bookstore materials and gained experience over the past 10 years. Please feel free to ask any questions you have about the photos. I highly recommend that you purchase these materials at this opportunity.
