RivetPrep

Independent, offline EPA Section 608 study preview for Android.

Built primarily for learners in the United States, and open to international learners studying the same English-language U.S. EPA Section 608 material and refrigeration concepts. Your region does not change the question bank. This pack does not cover another country's certification or licensing requirements; check the rules where you work.

Read 24 substantive offline lessons and practice with 500 original questions across Core and Types I, II and III. Lessons include worked examples, key points and glossary terms, stored directly in the app. Review explanations, use flashcards and bookmarks, make notes, and follow a personal study plan. Study data stays on your device. No accounts, ads or purchases.

The original lessons, practice questions and conceptual exercises have not been reviewed by a qualified HVAC/R expert. This app is not an official exam, a certification course or a pass guarantee.
