How the ExAC actually asks questions
The shortcut also drops the most underestimated part of preparation: how the ExAC frames a question. Reading the references prepares the content side. The question side is its own skill, and it does not come from reading.
Scenarios, not recall
Almost every ExAC question is a short scenario. The examiners describe a project situation in two or three sentences and ask you to apply a rule, a chapter, or a clause to it. The wrong answers are not absurd; they are realistic distractors that a working intern might believe based on intuition or partial reading. The exam rewards candidates who can read the scenario carefully, eliminate the implausible options, and select the one that best fits Canadian practice. Re-reading CHOP cover to cover a second time does not sharpen that skill; drilling scenarios does.
Time pressure is the differentiator
A common pace is roughly 60 to 90 seconds per multiple-choice question, depending on the section. Working architects who read the references at desk pace are often surprised by how quickly the clock moves in the exam room. The reading-to-recall gap is widest in Section 2, where a tabbed NBC still has to be navigated under time pressure, and in Section 4, where CHOP scenarios pack three or four reasonable-looking answers into the same question.
Open book is narrow on purpose
Only Section 2 (Codes) is open book. Only NBC 2020 and NECB 2020 are permitted. CHOP, CHING, CCDC 2, RSMeans, Yardsticks, your own notes, sticky annotations, and electronic devices are not allowed in the room. If your study plan treats CHOP and CHING as a quasi-open-book reference, the exam day will be the moment you discover otherwise.
