Disclaimer
What goraedu is and is not, and why you should always check the official rules.
Independent education website
goraedu is independent. It is not affiliated with, endorsed by or connected to any government agency, testing company or certifying organization, including the U.S. EPA. Certification and organization names are used only to identify the exams and sources we describe.
Not the official exam
Our practice questions are written by us from official sources. They are not questions from any real exam, and a good score on goraedu does not guarantee that you will pass. Certification requires passing the official test from the organization or agency that gives it.
Not legal or compliance advice
goraedu explains rules for study purposes. It does not tell you what a specific job, employer, state or local authority requires. State and local rules, manufacturer instructions and workplace safety rules may add requirements beyond the rules we cover.
Rules change
Agencies update their regulations from time to time. We show the date each page was last checked, but the official text, such as the eCFR or the agency's own site, is always the final word.
Tools and calculators
Any calculator on goraedu is for learning. Do not use its results as the only basis for real work. Follow the applicable rules, the equipment manufacturer's instructions and safe work practices.
