Michigan scores state law inside the trade exam itself - PA 407, PA 230, and Part 8 rules aren't a separate quiz here, they count toward your 75%. And the reference rules are stricter than most states: the NEC Handbook is explicitly prohibited, only a factory-tabbed code book is allowed in.
Straight answer, because it affects what you should study elsewhere. VoltMark's question bank is written to the National Electrical Code. It does not contain questions on 2016 PA 407, 1972 PA 230, or the Michigan Electrical Code Rules Part 8 — and those are scored inside your 80-item exam, toward the same 75%. Study those from the state materials you are allowed to bring.
Michigan also amends the NEC through Part 8. Where Part 8 changes a requirement, the Michigan-correct answer can differ from the national code answer our explanation gives. Treat our NEC practice as what it is — national code navigation and application drill — and check Part 8 for anything Michigan modifies.
Open book per the current PSI bulletin, with those specific reference limits. The exam is written knowing you have the code - the skill being tested is finding the right section fast and applying it under the clock. That's trainable, and timed practice in the real format is how you train it.
Exam details change. Always confirm the current format, references, and code edition with the official PSI candidate bulletin before test day.
