Practice benchmark only: PSI publishes a 70% passing standard for the Texas ACR exams (Environmental Air A: 120 scored + 5 pretest, 230 minutes, open book; Environmental Air B: 100 + 5, 170 minutes; Commercial Refrigeration A: 120 + 5, 230 minutes, B: 100 + 5, 170 minutes; Certified Technician: 60 + 4, 112 minutes). This practice exam flags 70% as a PRACTICE BENCHMARK ONLY, set to mirror that published standard; this 120-question, 230-minute draw mirrors the Environmental Air Class A exam’s length and time. It is a study signal, not a PSI result.
