The BCIN exams BCIN Prep covers
Study plan that works for open-book code exams
- Learn the map: Building Code Act sections, then Division A (compliance, objectives), B (technical) and C (administrative).
- Practise by topic and read every explanation - each one names the section, so you build the habit of looking it up.
- Tab or bookmark the sections you look up most; speed matters more than memory.
- Do full timed mocks (70 questions, 3 hours) until you finish with time to spare and score well above 70%.
- Review every missed question, then redo the topic.
