In the Hazardous Materials Engineer's Examination, many questions were given repeatedly from past questions.
For this reason, we believe that it is a shortcut to passing the examination to solve the past questions efficiently and learn the contents.
This book summarizes the necessary contents to solve the "past questions" in "text", and has "correct answers and explanations" to respond to [why?] [why?] [why?] after solving the "past questions".
Because it is organized by item, it is easy to organize in your mind. You can memorize and solve without consciousness by repeating "memorizing" → "solving problems" → "confirming correct answers and explanations" → "memorizing". In addition, you can pass the examination by repeatedly challenging.
