Practice benchmark only: PSI publishes the Mississippi HVAC specialty examination at 80 questions, 4 hours (240 minutes), open book, with a 70% passing standard; this practice exam flags 70% as a PRACTICE BENCHMARK ONLY, set to mirror that published standard, and its 80-question, 240-minute draw matches the real exam’s length and time. It is a study signal, not a PSI result.
