Can you imagine prepping for a national exam using a decade-old gaming console? Tech YouTuber "Yamakawa Teruki" recently dropped a challenge video on his "Yamakawa Sanpo" channel, revealing how he snagged the "Class B-4 Hazardous Materials Handler" national certification with nothing but a Nintendo DS educational game: "Honki de Manabu LEC de Goukaru DS Kikenbutsu Toriatsukai-sha Otsushu 4 Rui".
The challenge came with three ironclad rules: First, the DS software had to be his primary study material. Second, he could only peek at a limited number of online practice questions and past exams. And third, standard tools like notebooks or non-specialized dictionaries were fair game. While the software packed about seven hours of lectures and mock tests, its age meant the content was a bit out of sync with current exams, making the whole prep even tougher.
The exam itself covers fundamental physics and chemistry – no walk in the park for non-specialists. To bridge the knowledge gaps from the outdated software, Yamakawa wisely consulted Wikipedia for supplementary info and meticulously crafted over 120 pages of notes. Through sheer grit and round-the-clock dedication, he aced the test and officially earned his certification.
In the video, he candidly admitted, "Prepping with just a DS would've been brutal without smartphone assistance." His advice for future test-takers? "It's probably safer to just grab a textbook from the bookstore." The video clearly struck a chord with viewers, who flooded the comments with praise like: "The dedication in the latter half is insane!", "Made me wanna cry!", "Taking a DS to the exam is just too wild!", and "This video was totally worth it!"
Yamakawa is also active on X (formerly Twitter). His channel also chronicles his epic journey of traversing Japan using only local train lines, showcasing his incredible perseverance and creativity – truly inspiring stuff!
