Can You Pass All 4 ExAC Sections With Only One Month of Studying?

The good news: yes, some candidates do pass all four ExAC sections on only one month of focused study, and the reason it is possible at all is the competency-based cut score. You do not need to answer every question correctly; you need to perform well enough across the tested objectives in each section. In our years of working with Intern Architects through every sitting, our team at Examitect, an independent ExAC prep platform unaffiliated with the CACB, has seen that one-month passes share three traits: meaningful Canadian practice experience, full-time focus in the final stretch, and heavy use of timed practice questions. Treat one month as a sprint, not a shortcut.

Key Takeaways

What a realistic one-month ExAC plan looks like.

  • The ExAC cut score is what makes one month possible. The exam is scored against a competency-based cut score, not a fixed percentage, so the goal is enough across the tested objectives, not perfection. The ExAC 2026 exam guide walks through the format and scoring in detail.
  • Plan for 150 to 220 hours of focused study in 30 days. That is 35 to 55 hours per week, which is why most one-month candidates take time off work for at least the final fortnight.
  • Practice questions, not re-reading, are how recognition becomes recall. Aim for 1,200 to 1,800 timed practice questions across the four sections plus at least one full timed mock exam.
  • Split the sitting if your situation does not support full-time study. Pairing Sections 1 and 2 first, then Sections 3 and 4 later, is the safer one-month plan for most working Intern Architects. See all four sections in one sitting for the trade-offs.
  • Triage the reference list hard. Read CHOP key chapters (3, 5, 6, 8, 11, 12), use CHING for visual recall, and tab NBC 2020 plus NECB 2020 in Week 1.
  • Section 2 is the most predictable to pass in a short cycle. It is open book, and timed scenarios against a tabbed NBC 2020 build the right reflex fast. The Section 2 overview covers what to drill.
  • Take time off work for the final push. Treating Days 20 through 30 as a full-time study job is what separates the candidates who pass on one month from the ones who run out of runway.

Who actually pulls off a one-month ExAC pass?

The honest answer is that one-month passes are a minority outcome, and the candidates who manage them share a recognisable profile. They are not necessarily smarter or more naturally gifted; they have stacked specific advantages that make a 30-day cycle realistic. If you are weighing a one-month plan, the most useful thing you can do is compare yourself to the profile honestly before you book the date.

Profile A

The seasoned working Intern

Has logged three or four years of Canadian practice across a mix of design, code review, and contract administration. Already familiar with CHOP language, NBC structure, and CCDC 2 mechanics from the day job. Needs the month to consolidate, not to learn from scratch.

Profile B

The full-time studier

Has taken study leave, a sabbatical, or parental leave that brackets exam day. Treats the month as a 40 to 50 hour per week job with weekends. Has the focus to put in deliberate hours, not just calendar time.

Profile C

The recent ExAC retaker

Sat the ExAC within the past 12 months, passed two or three sections, and is returning to clean up the remaining one or two. Already has the reference shelf, the tabbing system, and the question bank from the first cycle.

Profile D

The systems-thinker recent grad

Recently graduated from a CACB-accredited program, completed the IAP hours, and still has academic recall on assemblies and codes from school. Has the study endurance habit and no work conflicts.

If none of these four profiles fits you, a one-month plan is a stretch and a split sitting is usually the better call. The good news is that the cut score and the question-heavy method below still apply on a two-sitting timeline; only the calendar changes.

The cut score is what makes one month possible

The single most important piece of ExAC math to internalise on a short cycle: you are not chasing 100 percent. The examination committee sets a competency-based cut score for each section, calibrated per sitting. You pass by performing well enough across the tested objectives, not by answering every question correctly. That changes how you study.

Practically, the cut score has three implications for a one-month plan. First, the goal is breadth coverage to a pass threshold, not depth mastery of any one chapter. Second, repeated exposure to the question style matters more than re-reading, because the cut score rewards recognition of patterns under time pressure. Third, you can afford to skip a small share of the highest-difficulty topics in a section if you are solid on the rest; you cannot afford to leave whole topic areas untouched.

If you tried to memorise everything What a cut-score plan does instead
Read CHOP cover to cover in three weeks; run out of time for Sections 2, 3, and 4. Read CHOP Chapters 3, 5, 6, 8, 11, and 12 closely; skim the rest; pair every chapter with practice questions.
Memorise NBC clause numbers by rote. Tab NBC 2020 Parts 3 and 9 plus NECB 2020 envelope sections; drill timed Section 2 scenarios against the tabs.
Skip practice questions because they feel like the test. Run 1,200 to 1,800 timed questions and treat misses as the study list.
Avoid the mock exam to protect your confidence. Sit one full timed mock in the final week; use the result as a diagnostic, not a verdict.

Section 3 is the place candidates most often over-write the short-answer prompts. Lift content density, drop ornate prose, and trust the rubric to reward the specific facts you put down.

A 30-day ExAC plan, week by week

The schedule below is the version of the one-month plan our team shares with candidates who fit one of the four profiles above. Adjust the section order to match where you are weakest; the volume targets stay roughly constant.

Days 1 to 2
Diagnostic mock and reference triage

Sit a short cross-section diagnostic to surface your weakest area. Pick the references you will actually open: CHOP key chapters, CHING for visual recall, NBC 2020 plus NECB 2020 for Section 2, CCDC 2 and RAIC Document 6 for Section 4. Plan to skim or skip the rest.

Days 3 to 10
Section 1 deep work plus CHOP key chapters

Read CHOP Chapters 3, 5, 6, and 8 (programming, site, cost, schematic design, design development). Pair each chapter with 40 to 60 timed multiple-choice questions on the same topic. Use CHING for assemblies and building science. Target 40 to 50 study hours across the week.

Days 11 to 17
Tab NBC 2020 and drill Section 2

Place permanent printed tabs on NBC 2020 Part 3 (fire and life safety, spatial separation, accessibility) and NBC 2020 Part 9 (small buildings), plus NECB 2020 envelope and energy sections. Drill timed Section 2 scenarios every day until you can find any clause in under 30 seconds.

Days 18 to 25
Section 3 short answers and Section 4 contracts

Drill short-answer prompts on sustainability literacy and integrated code application for Section 3. For Section 4, read CHOP Chapters 11 and 12, CCDC 2 General Conditions GC 1 through GC 12, and RAIC Document 6, then run scenario questions on bidding, construction administration, and project management.

Days 26 to 27
Full timed mock exam and gap review

Sit one full timed mock exam under realistic exam-day conditions. Score it, identify the two or three topics still costing marks, and run one targeted question set per gap. Do not start any new reading at this point.

Days 28 to 30
Light review, sleep, exam day

Taper to short review sessions: FAQ-style recall, your own gap notes, a quick re-check of NBC tabs. Stop new content 48 hours out. Sleep, hydrate, and arrive 30 minutes early on exam day with photo ID, your confirmation, and only the permitted materials. The practice questions vs mock exams post covers the final-week mock-and-taper rhythm in detail.

Reference triage when you only have 30 days

The official ExAC Preparation Guide lists four primary references (CHOP, IAP, NBC 2020, NECB 2020) and a long supporting list. On a three-month plan you can work through most of it. On one month you cannot, and that is fine. Triage is the point.

Examitect's recommended primary list for ExAC 2026 is CHOP, CHING, NBC 2020, and NECB 2020. We swap the IAP for CHING because the IAP guidebook describes the internship every candidate logs between graduating and writing the ExAC; it is the rulebook for your hours, not the textbook for the exam. CHING, by contrast, anchors Section 1 and Section 3 questions on assemblies, building science, and materials. The trade-off is hours, not dollars; CHING returns more marks per study hour than the IAP.

Reference One-month treatment Approximate hours
CHOP Read Chapters 3, 5, 6, 8, 11, and 12 closely. Skim the rest. Pair every chapter with practice questions. 25 to 35
CHING Visual recall on assemblies, structure, envelope, and building science. Flip through; do not read cover to cover. 10 to 15
NBC 2020 Tab Parts 3 and 9 in Week 1; drill Section 2 scenarios against the tabs daily after. 15 to 20 (tabbing) plus drilling
NECB 2020 Tab envelope and energy sections; drill envelope and energy questions. 4 to 6
CCDC 2 Read the General Conditions GC 1 through GC 12 and the price/payment articles. Skip the appendices. 4 to 6
RAIC Document 6 Read once with focus on architect-as-Consultant duties and the schedule of services. 3 to 5
Yardsticks and RSMeans Cost questions on the exam supply their own data tables. Drill the method on practice questions; do not memorise line items. 2 to 3
IAP guide Skip. The IAP describes the internship hours every candidate logs before sitting the ExAC; the exam itself does not test the guidebook directly. 0

Roughly half of the 150 to 220 plan hours go to references; the other half goes to practice questions and the mock exam. If you find yourself reading more than that, you are studying the way a three-month plan would and you will run out of runway. The ExAC resources to focus on post has the full tier framework if you want the longer version.

Why practice questions beat re-reading at this scale

Reading builds recognition; practice builds recall. The ExAC tests recall under a clock, so on a 30-day cycle, every hour you spend reading instead of practising is an hour spent on the lower-yield activity. This is the single biggest mindset shift the one-month plan demands of working Intern Architects, because reading feels like study and practice feels like risk.

Three things to lock in about question practice on a one-month plan. The first is volume: aim for 1,200 to 1,800 timed questions across the four sections by exam day. The second is timing: do questions against a clock from Day 3, not from Day 20, so that pace becomes automatic rather than a final-week panic. The third is the review loop: every missed question turns into a study target. Go back to the source reference, read the relevant chapter section, and re-attempt a similar question two days later.

The pattern recognition that this method builds is what the cut score actually rewards. After a few hundred questions on Section 2, you will recognise the shape of a spatial separation problem from the first sentence and know which NBC Part 3 table to open. After a few hundred questions on Section 4, you will spot a CCDC 2 GC 5 payment scenario in the stem before reading the options. That speed is what frees up time on the real exam to think about the genuinely hard questions. The ExAC exam hacks post goes deeper on the pattern-recognition method.

Where one-month candidates lose marks

Every ExAC cycle, the same reference-side mistakes show up in the post-exam debriefs our team runs with candidates on short plans. Reading them now is cheaper than discovering them after the fact.

  • Trying to read every primary reference cover to cover. On 30 days, that is the path to four half-finished books and a half-prepared exam. Triage hard, name the chapters you will actually read, and accept that you will skim the rest.
  • Starting practice questions in Week 3. Saving questions for the last stretch is the most common short-cycle mistake. Start question practice in the first week so the pattern recognition has time to compound.
  • Tabbing the NBC without drilling against it. A tabbed NBC 2020 that you never opened under time pressure is decoration. The tabs only earn their place if you drilled Section 2 scenarios against them every week of the plan.
  • Treating Section 4 as the easy section because of work experience. The Section 4 project management deep dive shows where work experience trips up Section 4 first: the exam tests Canadian contract structure and CHOP language, not your firm's project habits. Drill CHOP Chapters 11 and 12 and CCDC 2 GC 1 through GC 12 in week three.
  • Writing essays in Section 3 short-answer prompts. The rubric rewards specific content density, not eloquence. Answer the exact question, use Canadian terminology, and stop.
  • Skipping the mock exam because the score might be ugly. The mock is a diagnostic, not a verdict. Most candidates on a one-month plan see a tight or borderline mock score; the value is in the gap list it produces, not the percentage.
  • Underestimating sleep in the final week. Cognitive performance under time pressure collapses on six hours of sleep. Protect eight hours from Day 27 onward, even if it means cutting a study session short.

When to take time off work for the final push

The hardest part of a one-month plan for working Intern Architects is the hour count. At 35 to 55 hours of study per week, the plan is a second full-time job stacked on top of the first. Most candidates who pull off a one-month pass solve this by taking dedicated study leave for at least the final two weeks. If you can afford to, treat the last fortnight as a full-time study job and treat exam day as the final deliverable.

If your firm has a study-leave policy, use it. If not, the conversation with your principal is worth having; many Canadian firms support ExAC study leave informally because licensure benefits the firm too. Two practical formats that work: a full two-week block ending the morning of the exam, or a four-day work-week across the last three weeks plus a full final week off. Pick whichever your home schedule and project deadlines actually allow.

If taking time off is not realistic this cycle, the safer call is to split the sitting. Pair Sections 1 and 2 first, take the second sitting later in the year, and use the longer runway for Sections 3 and 4. The pass standard is identical and your overall risk drops; only the calendar shifts. The best ExAC study schedule post lays out the time math across plan lengths.

When you should not try a one-month plan

Honest read on when to push the date or split the sitting instead. Any one of these by itself is reason to reconsider; two or more is a clear signal.

  • You cannot consistently put in 35 hours of study per week. The plan does not flex below that. If your weekly ceiling is 15 to 20 hours because of work and family, you need 10 to 12 weeks, not four.
  • You have limited Canadian practice exposure. If your day-to-day work has not put you in front of NBC tables, CCDC 2 administration, or schematic design decisions, one month does not give you time to build that base.
  • You do not have access to a Canadian practice question bank. The plan rests on 1,200 to 1,800 timed questions. Without a bank, you are reading instead of practising, and reading is the lower-yield activity.
  • You have major life events in the 30 days. Moves, weddings, parental leave, and busy seasons at work all break the plan. Pick a quieter month or extend the runway.
  • You are returning after a long break from study. If it has been more than a year since you opened a textbook, give yourself 8 to 12 weeks. The first two to three weeks of any plan are mostly about rebuilding study habit.
  • You want zero risk of failing a section. One-month plans trade higher single-attempt fail risk for a shorter cycle. If a re-sit would derail your registration timeline, choose the longer plan.

None of this is a verdict. Most candidates who do not fit the one-month profile pass comfortably on the 12-week ExAC study schedule, which uses the same cut-score logic and question-heavy method spread across a more humane calendar. Choose the plan length that fits the life you actually live, not the one that fits the exam date you wish was sooner.

FAQ

One-month ExAC plan FAQ

Yes, some candidates pass all four ExAC sections after only one month of focused study, but they are a minority and they share specific traits: strong prior Canadian practice experience, the ability to study full-time, and heavy use of timed practice questions. For most working Intern Architects, one month is high-risk; for candidates with the right runway and a willingness to take time off work, it is workable on a cut-score exam.

A one-month ExAC plan typically requires 150 to 220 hours of focused study, split roughly half on references and half on practice questions and mock exams. That works out to 35 to 55 hours per week, which is why most candidates who pass on a one-month plan take time off work for at least the final two weeks.

For most candidates with one month, splitting the ExAC into two sittings is the safer choice. Pairing Sections 1 and 2 first, then Sections 3 and 4 later, lets you go deeper on each pair. Sit all four at once only if you already have strong familiarity across every competency area and can commit to a full-time study block.

Most candidates who pass all four ExAC sections after one month of study take at least one to two weeks off work in the final stretch. Treating the last fortnight as a full-time study job is what makes the plan realistic. If you cannot take time off, the safer call is to split the sitting or push the exam date back.

Plan for at least 1,200 to 1,800 timed practice questions across the four sections in a one-month ExAC plan, plus at least one full timed mock exam. Question practice is where recognition turns into recall, and the ExAC rewards recall under time pressure. Review every missed question against the source reference and re-attempt it later in the cycle.

A working Intern Architect can pass the ExAC in one month if they have meaningful exposure to Canadian codes, contracts, and contract administration in their day job, and if they can carve out evening and weekend hours plus at least one week of dedicated study leave near the exam. Without one of those two ingredients, a one-month plan rarely produces four passes.

In a one-month ExAC plan, focus on CHOP key chapters (programming, cost, schematic design, contract administration, project management), CHING for visual recall on assemblies and building science, and a tabbed NBC 2020 plus NECB 2020 for Section 2. Skip cover-to-cover reads of every primary reference; the ExAC tests application across all four sections, not exhaustive memorisation of any one source.

The ExAC uses a competency-based cut score set by the examination committee, not a fixed percentage. You do not need to answer every question correctly to pass; you need to perform well enough across the tested objectives in each section. The cut score is calibrated per sitting, which is part of why heavy practice and pattern recognition help more than perfectionism.

Yes. Write at least one full timed mock exam in a one-month ExAC plan, ideally between Days 24 and 27. The mock calibrates your pacing, surfaces fatigue patterns, and gives you a final diagnostic on which topics still need a fast review pass. Candidates who skip the mock because they fear a low score lose the most valuable signal of the cycle.

If you fail one section after a one-month ExAC plan, your passes on the other three sections still carry. You re-sit only the failed section at the next available sitting, study only that section, and most candidates who fail once pass on the next attempt. A one-month plan trades a higher single-attempt fail risk for the chance to finish faster.

Yes, one month is enough time to tab the NBC 2020 effectively for the ExAC, as long as you do it in the first week and then drill Section 2 scenarios against the tabs every week after. Tabbing without drilling is decoration; tabbing plus repeated timed scenarios is what makes the open-book Section 2 actually open.

No. A cover-to-cover read of CHOP is not realistic in one month and is not the best use of study hours. Read CHOP Chapters 3, 5, 6, 8, and 11 closely, skim the rest, and pair every chapter with practice questions on the same topics. The questions, not the reading, are where the marks come from in a short cycle.

A three-month ExAC plan has room for a full first-pass read of CHOP and CHING, a longer NBC tabbing cycle, two mock exams, and a built-in buffer week. A one-month plan compresses everything around practice questions and targeted reading on weak topics. The pass standard is identical; the path is just denser. See the three-month ExAC study plan for the longer version.

Section 2 is the section where one-month candidates most often pass, because it is open book and the NBC 2020 and NECB 2020 are the only permitted references. Tab the codes in Week 1, run timed scenarios on fire and life safety, spatial separation, accessibility, and small buildings, and Section 2 becomes the most predictable of the four to plan around.
