About this app

Prepare for the EPA 608 exam with practice tests and answer explanations in English, Spanish or Russian. Study Core and Types I, II and III, the four sections covered by Universal certification.

BUILD YOUR UNDERSTANDING
Practice refrigerant fundamentals, small appliances, high-pressure systems and low-pressure systems. Review answer explanations and use the glossary to reinforce terminology.

PRACTICE AT YOUR PACE
Work through practice questions, review your answers and see your results by category. Return to saved attempts to continue studying.

TRY A TIMED MOCK EXAM
Practice with 100 questions: 25 each from Core, Type I, Type II and Type III. The mock uses a two-hour practice timer and includes a link to a pressure-temperature reference chart. Real exam timing and rules vary by testing provider.

STUDY IN YOUR LANGUAGE
Switch between English, Spanish and Russian. These are study languages in this app; they do not establish which languages your testing provider offers.
