How to use it in your final week
- Front-load A/C System & Component Diagnosis, Service & Repair — at 25 of the 40 scored questions it is about 50% of the test on its own, so if you master one section from the sheet, make it this one.
- Then work Operating Systems & Related Controls Diagnosis & Repair (10 of 40) — the sheet leads there with blend (temperature) door.
- Then work HVAC Systems Diagnosis, Service & Repair (incl. Refrigerant Handling) (8 of 40) — the sheet leads there with system-level performance testing.
- Drill the reversal traps until they are reflex — the most commonly flipped one on this test is both gauges reading the SAME low pressure = system essentially EMPTY, not a compressor problem.
- Read the sheet the morning of your appointment for a last pass on the memory hooks, then answer every one of the 50 questions — 10 are unscored research items and you are not told which.
