This is a set of 7 DVDs covering the 6 main subjects for civil servant exams, purchased around 2015. All items are included. I have confirmed that they work (played the beginning of each disc and read the data on a PC) and they can be viewed without any problems. The content consists of a carefully selected collection of past exam questions, with explanations and answers provided by the instructors. In addition to the video data, PDF data such as past exam question collections, texts, and explanation summaries are included. I believe that subjects like the constitution and numerical reasoning are still relevant for current exams. (Even the civil code is based on past exam questions, so it should still be useful.) The DVDs can be played at double speed, so they are recommended for those who want to study efficiently. #CivilServantExam #EntranceExam #DVD #HomeStudy
