- Japanese乙種 hazardous-materials exam candidates
- Worth noticing
- The site says each original question identifies the law or material property it is based on; corrections are listed in a public errata section.
Field notes
The homepage says the questions are independently written from laws and the properties of each material, since only some official exam questions are publicly released. It says each item identifies its basis and directs users to an errata and update-history section for corrections. The listed乙4 mock uses the stated 35-question, two-hour format, while the other-class exemption guide describes a 10-question, 35-minute route.
