Although I had taken basic forensics-related classes, the only study materials I actually studied before the certification exam were this summary book and the past exam questions provided by the society. I memorized the important concepts and frequently appearing parts in the summary book, and focused on studying the parts that I personally thought were weak. I solved the past exam questions mainly on the weak parts, and took the exam.. I passed the written test on the first try, which I took to check my level.ㅠㅠ Thank you. If I know anyone who is looking to get a certification, I will definitely recommend it!
