Thanks to the instructor's enthusiastic support, I succeeded on my second attempt. Having taken the exam twice recently, I feel that the questions have become much more difficult than before. If you have no prior knowledge of digital forensics, this lecture is, of course, a must-take, and it seems additional study is needed to grasp the latest security trends. In particular, participating in academic conferences and acquiring knowledge in that year seemed to be the most effective strategy for hitting the right answers. For legal knowledge questions, you must also take this lecture. Additionally, you should study unusual forensic precedents. I recommend studying basic legal knowledge through the lecture and then purchasing books to study case precedents. As the instructor always says, the exam is not standardized. Recent trends suggest it's becoming increasingly difficult, so to achieve the passing score of 60 points, this lecture is not an option but a necessity. Beyond just knowledge, the tips provided by the instructor are also extremely useful. Lastly, I want to thank the instructor once again for making it feel like I was attending a dedicated class for every exam. Thanks to this, I passed and am now one step closer to my dream.
