## What is Refrigeration License 1/2/3?

Japanese-language original practice for Japan Refrigeration Machinery Supervisor Classes 1, 2 and 3.

Shared foundational questions and course-specific calculations are included. This is not a reproduction of past papers or a claim of complete exam coverage. Class 1 academic practice uses drafts, model answers and self-checks. It is not automatically graded and does not predict an overall exam pass. Drafts stay on the device.

Each course keeps its own progress and exam date. One non-consumable Pro purchase unlocks every included course in this app; existing owners retain access and can restore the same purchase. Free access includes 10 lifetime drill/written attempts per course, one half mock per course and a three-day passive-study trial. Full mocks, unlimited weak review and unseen-only practice require Pro. No subscription.

Unofficial app by Particles and Waves. Not affiliated with the government or exam administrators. Scores are learning guidance, not a guarantee of passing. All study content is in Japanese.
