Getting your EPA 608 card comes down to four sections and one number: 18 out of 25 on each one. EPA 608 Pro gets you there with 1,025 questions, full exam simulators, and explanations that tell you why an answer is right instead of just marking it wrong. EXAM SIMULATORS Core, 25 questions Type I Certification, 50 questions Type II Certification, 50 questions Type III Certification, 50 questions Universal, 100 questions Core is required for every certification, so testing for one Type means sitting 50 questions rather than 25. The simulators match that. Each section is scored on its own, so you find out you are solid on Core and shaky on Type II while there is still time to do something about it. 1,025 QUESTIONS Seven categories and 41 subtopics: ozone science and federal regulations, refrigerants and refrigeration fundamentals, recovery and evacuation, safety and cylinders, and all three appliance Types. Every question comes with an explanation, and most of them name the exact mistake the question was written to catch. The 80 and 90 percent recovery rules, Table 1 evacuation levels, leak rate thresholds, the 200 pound line, 25 mm Hg absolute. These are the details people fail on, and they are covered. STUDY TOOLS Flashcards for every category, one fact per card Practice tests with answers and explanations as you go A diagnostic test that finds your weak spots Missed question review that keeps working what you got wrong Topic quizzes for any of the 41 subtopics Custom quizzes across whichever categories you pick A glossary for the abbreviations and jargon in the questions Progress tracking by category and subtopic WORKS OFFLINE Every question, explanation, and diagram lives on your device. Study in a mechanical room, a basement, the van, or anywhere else with no signal. FOR HVAC techs, apprentices, trade school students, and anyone testing for Core, Type I, Type II, Type III, or Universal certification.
