BCIN Exam Sample Questions and Practice Tests

What the Ministry and Humber do publish

That last item is the closest thing to official feedback on specific questions, and it only goes to the candidate who appealed.

Why leaked "dumps" are a bad idea

You will find files on document sharing sites that claim to be recalled BCIN questions. Avoid them, for four reasons.

1. They break the exam rules. Humber's candidate protocol lists disclosing "the nature or content of any question" as misconduct, along with copying or removing exam materials. The penalties include a Fail result and a forfeited fee, with an incident report sent to the Ministry.

2. They are often wrong. A recalled question is someone's memory of a stem, without the exact wording or numbers, and the "answer" is their guess. Usually nobody has checked it against the code.

3. They are probably out of date. Exams switched to the 2024 Building Code on March 30, 2026. The 2024 code adopts the 2020 National Building Code with Ontario amendments and, according to the province, eliminates at least 1,730 technical variations between the provincial and national rules. Questions built on 2012 articles can point you to the wrong number or the wrong answer.

4. They train the wrong skill. The exam is open book. Memorizing answers to questions you may never see does little. Finding the right article in under 2.5 minutes is what moves your score.

What good practice questions look like

Whether you use ours or someone else's, look for these:

• Built on the 2024 code. Every answer should cite a 2024 article, such as Division B 9.8.8.3, not a 2012 reference.
• Mapped to the syllabus. Questions should fall inside your exam's study guide and avoid the excluded articles.
• A citation for every answer. You should be able to open the code and confirm the answer yourself.
• An explanation of the wrong options. Knowing why the other three choices are wrong is how you learn to spot distractors.
• Realistic format. Four options, one best answer, a mix of lookups, scenarios, calculations and table questions.
• A timer. Practice at about 2.5 minutes per question, and full 70 question runs of 3 hours.
• A way to report errors. Every question bank has mistakes. Good ones fix them quickly.

How to use practice questions well

1. Start untimed, by topic. Work through one syllabus section at a time and check every answer against the article.
2. Note your search terms. When you find an answer, write down what you searched for. Those notes become your exam-day search list.
3. Move to timed sets. Sets of 20 questions in 50 minutes build pace.
4. Finish with full simulations. 70 questions in 3 hours, with no pausing, in conditions close to the real thing.
5. Review every miss by finding the article, not just by reading the answer.

Our guide How to Pass the Open Book BCIN Exam explains the search and pacing method in more detail.

Write your own questions

A useful exercise is writing your own questions from the code. Pick an article in your syllabus, write a question whose answer is a number or rule in it, then write three wrong options from nearby sentences. It forces you to read the exceptions and the table notes, which is where many answers turn.
