Store listing
By AHDS, from Google Play“Section 608 exam prep with hundreds of questions, PT charts, and smart practice.”
Description by AHDS Written by the developer, not by AppBrain. Click to read.
Hundreds of Practice Questions Study from a massive question bank covering all four exam sections: Core, Type I, Type II, and Type III. Every question has four answer options and a detailed explanation, just like the real exam. New questions are added regularly.
Pressure-Temperature Chart Questions Practice reading PT charts the way you will on the real exam. An interactive chart covering R-22, R-134a, R-410A, R-404A, and R-32 is built right into the questions. Calculate superheat, subcooling, identify refrigerants, and compare pressures across different refrigerants.
5 Study Modes Per Section
Cram Mode - Read through every question with the correct answer and explanation shown. Absorb the material before testing yourself.
Study - Answer questions at your own pace with instant feedback. Your position is saved so you can pick up where you left off.
Smart Practice - The app tracks what you get wrong and builds focused sessions around your weak spots. 75% of questions come from your weakest areas, 25% from material you haven't seen yet. Questions you master (3 correct in a row) are excluded so you spend time where it matters.
Mock Exam - Simulate the real exam with 25 random questions. 72% required to pass, just like the actual certification test. Review your answers with full explanations after each attempt.
