What is the format?

Humber describes Ontario Building Code exams as open-book, 3 hours, with 70 multiple-choice and true/false questions.

What is the biggest study mistake?

Studying only standalone mechanical topics and missing the fire-safety, shaft, and service-space crossover rules that change the answer.
