I passed the 24th exam, and the various practice images provided, exam review videos, etc., were very helpful! As a major, I studied extensively, including academic books (from 2019 publications to recent ones), but I believe I definitely built my foundation on Inflearn. Thank you very much. I highly recommend it as an essential course for those getting into forensics. Don't get discouraged, and if you keep at it steadily, you'll get good results. Fighting!
