So I just got my results back yesterday and I'm still kind of in disbelief. Passed with an 82 after failing my first attempt in March with a 71. If you're prepping right now and feeling discouraged, stick with me because I made some pretty dumb mistakes the first time around that I think a lot of people repeat.
The biggest thing that changed my second attempt was actually using a decent S 13 practice test instead of just re-reading the manual cover to cover. I was scoring in the high 70s on practice exams and thought that was good enough — it wasn't. The real exam has these situational questions that trip you up if you haven't drilled them specifically. I probably did 400+ practice questions over six weeks leading up to my retake.
I also leaned heavily on an S 13 study guide that broke down the regulatory sections by topic rather than just chapter order. That structure helped me connect concepts I kept mixing up. Anyone else have specific topics they struggled with? The hazmat communication section nearly wrecked me both times.
