Book updated May 2024. There are code related questions that are state specific (NMAC, IBC, IRC…etc). At the same time, technical questions are almost always based on the NRCA/OSHA recommendations and requirements. We create these supplemental self-practice test questions module referencing the principles and concepts currently valid in the corresponding trade. Each question comes with an answer and a short explanation which aids you in seeking further study information. These questions are intended as supplementary study material for fundamental knowledge establishment. They are NOT actual past-paper questions. You should use this product together with other study resources for the best possible exam prep coverage.
