Pass your EPA 608 the first time. Hundreds of real practice questions with clear explanations, and timed mock exams built to the actual Section 608 format. Works offline. No account, no sign-up. Studying for a test that is already booked? Open the app and take a practice sitting in the next ten minutes. EVERY SECTION OF THE EXAM • EPA 608 Core — the section every certification type requires • Type I — small appliances, sealed units with 5 lb of refrigerant or less • Type II — high-pressure: split systems, heat pumps, supermarket racks • Type III — low-pressure: centrifugal chillers and their recovery rules • HVAC Fundamentals — the refrigeration cycle, airflow and electrical basics Every deck is in the app today. Nothing is a placeholder, and nothing arrives later. MOCKS BUILT TO THE REAL FORMAT The federal rule builds every test as 25 Core questions plus 25 for each technical type. That is exactly how the mocks here are built: 50 questions for a single type, 100 for the full Universal sitting. Timed, graded instantly, with a full answer review afterwards. EVERY SECTION SCORED ON ITS OWN Each section is graded on its own at 70%. The federal rule sets a single 70% pass mark; certifying organizations typically administer and score Core and your technical type separately, so this app does too — you always know which one still needs work, instead of hiding a weak section inside a good average. EVERY ANSWER CITES ITS SOURCE Each question names the source it comes from, with its explanation. For regulatory questions that is the exact CFR section. SMART REVIEW REMEMBERS YOUR MISSES A five-box spaced-repetition system brings each question back right before you would forget it. Anything you miss jumps the queue with its explanation attached. KNOW WHEN YOU ARE READY Set your test date and the home screen shows a countdown beside your best mock score. The readiness gauge blends deck mastery with your best sitting, scoped to the certification you actually chose. WHO IT IS FOR HVAC apprentices and technicians, refrigeration and appliance techs, trade-school students, and building-maintenance staff — sitting the EPA 608 for the first time or adding another type. OFFLINE, PRIVATE, NO ACCOUNT No sign-up, no email, no ads. The whole app works with no signal, so you can study in the truck, in a mechanical room, or on a break. Your progress stays on your phone and never leaves it. NOT AFFILIATED WITH ANY AGENCY An independent study aid. Not affiliated with, endorsed by, or approved by the U.S. Environmental Protection Agency (EPA) or any EPA-approved certifying organization. Independent study material for the federal Section 608 technician certification. The exam itself is administered by EPA-approved certifying organizations, which set their own scheduling and fees. Practice scores are an estimate, not a guarantee.
