Pass your EPA Section 608 technician certification. 520 practice questions across all four exam sections — Core, Type I, Type II and Type III — written from EPA's published test topics and 40 CFR Part 82. WHAT MAKES THIS DIFFERENT Every answer cites its source. Get a question wrong and you don't just see the correct answer, you see the regulation behind it — 40 CFR § 82.152, § 82.156, § 82.157, or EPA's own published test topic outline. You learn where the rule lives, not just what it says. Current rules, not outdated ones. Leak-rate thresholds changed in 2016 to 30% industrial process / 20% commercial / 10% comfort cooling. R-22 production and import ended January 1, 2020. R-134a is a medium-pressure refrigerant, not high-pressure. A lot of study material still teaches the old answers. This doesn't. Real exam scoring. Each graded section exam is 25 questions and you need 18 of them — 70% — to pass, exactly like the real test. Questions are drawn proportionally across the section's topic areas. No inflated scores. Answers move. Option order is shuffled on every attempt, so you learn the material instead of memorizing that the answer is usually B. Full Spanish. Every question, every answer, every explanation and every screen, in Spanish. Switch languages any time. FEATURES • 520 questions across 26 EPA topic areas • Practice by topic — untimed, with the explanation shown as you go • Graded 25-question section exams with a real 70% pass bar • Review screen that shows what you missed first • Flashcards for every section • Bookmark the ones that catch you out • Per-topic accuracy tracking and a "study next" list of your weakest areas • Daily practice streak • Fully offline — no signal needed on the jobsite THE CERTIFICATION PATH Core is mandatory for every certification type, so the graded type exams stay locked until you pass it — the same way the real certification works. Pass Core plus your type to earn Type I, Type II or Type III. Pass all four sections for Universal. Type I covers small appliances of 5 lbs or less. Type II covers medium-, high- and very high-pressure appliances. Type III covers low-pressure appliances. PRIVACY No account. No sign-up. No ads. No tracking. No analytics. Your progress is stored on your device and nothing is ever sent anywhere. --- Not affiliated with, endorsed by, or sponsored by the U.S. Environmental Protection Agency or any certifying organization. This app is a study aid. Actual certification testing must be completed through an EPA-approved certifying program.
