📚 App Features & Study Modes

What exam does this app prepare me for?

The app helps you prepare for the EPA Section 608 Technician Certification exam, which is required for technicians who maintain, service, repair, or dispose of equipment that could release ozone-depleting substances or substitute refrigerants.

What exam categories are covered?

We cover all four sections of the EPA 608 exam:

• Core: Ozone depletion, the Clean Air Act, Montreal Protocol, safety rules, shipping, and recovery regulations.
• Type I: Small appliances (containing 5 pounds or less of refrigerant).
• Type II: High-pressure and very high-pressure appliances (like residential AC systems and commercial refrigeration).
• Type III: Low-pressure appliances (such as chillers).

How many questions are in the app?

The app includes 578 practice questions spanning the Core, Type I, Type II, and Type III categories, as well as digital flashcards for quick review.

Are these the actual exam questions?

No. Official EPA 608 exam questions are kept confidential by certifying organizations. Our questions are study aids designed to mirror the topics, difficulty, and format of the real exam to help you prepare effectively.

How does Mock Exam Mode work?

The mock exam simulates a real testing experience. It presents a timed set of questions across the different sections. You need a score of 70% or higher on each section to pass.

What are "Weak Questions"?

The app tracks which questions you answer incorrectly. It automatically resurfaces these questions during study sessions so you can focus on the areas where you need the most improvement.
