About

Refrigeration License 1/2/3

Features
Read full description

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. 第一種・第二種・第三種冷凍機械責任者を、ひとつのアプリで学習。 共通の法令・冷凍工学の基礎を復習し、第二種の学識計算、第一種の計算・記述演習へ進めます。学習記録と試験日は種別ごとに保存します。 収録内容 ・第三種:法令・保安管理技術の独自問題112問。 ・第二種:共通基礎112問と学識の計算40問(計152問)。 ・第一種:法令・保安の共通基礎112問と、学識の計算・記述28問。 共通基礎には種別をまたぐ同じ内容が含まれます。過去問集や試験全範囲の網羅をうたうものではありません。 模試と演習 第三種は法令20問・保安15問の35問、第二種は法令20問・保安10問・学識10問の40問。各科目60%以上を練習の目標にします。第一種の択一模試は法令・保安の35問が対象で、学識は別画面の5問演習(120分の目安)です。記述は草稿・解答例・確認項目による自己評価で、自動採点や3科目全体の合否判定は行いません。草稿は端末内に保存します。 法令の出典はe-Govの原文を表示。法令引用を2026年4月1日の条文と照合しています。計算問題は架空の条件による独自演習です。公式試験問題の転載ではありません。

Verdict

The call

The clearest difference is in-app purchases: AI先生基本情報技術者 at none against Refrigeration License 1/2/3's 1. Refrigeration License 1/2/3's advantage is ads (none vs shown) and update cadence (every 4 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
