BOABC Level 2 study plan
BOABC Level 2 · Give each week a clear focus.
8 weeks · About 7 hours per week
Building
Map the Building domain into a checklist of every code-topic area it covers, then rank each area by the exam weight you infer from the 50% split.
Read the Building occupancy-classification and construction-type material and write a one-page summary table of each class and type in your own words.
Define 25 Building-domain terms and write a plain-language definition plus one worked example for each.
Set up a spaced-repetition deck and enter the first 40 Building flashcards, tagging each by subtopic.
Your checkpoint
A ranked Building-domain topic checklist with the 25-term glossary and 40 tagged flashcards completed.
Building
Work through at least 60 Building-domain practice questions on egress, fire-resistance, and interior-environment topics, and log every miss with its root cause.
Rewrite each missed concept as a corrected rule statement of one or two sentences.
Sketch from memory the required egress-path components and dimension rules, then check your sketch against your source notes.
Explain aloud, without notes, how occupancy classification drives allowable height and area.
Your checkpoint
An error log of at least 60 attempted Building questions, with a corrected rule statement written for every miss.
Building
Drill the Building subtopics where week 2 accuracy fell below 70% until you reach 80% or better on a fresh set of 30 questions.
Compare structural-load and materials requirements across construction types and build a comparison matrix.
Practice 20 calculation-style Building items (area, height, occupant load) under timed conditions.
Recite the key numeric thresholds (travel distance, stair width, fire ratings) from memory and note any you cannot recall.
Your checkpoint
A construction-type comparison matrix plus a timed 20-question calculation set scored and reviewed.
Building
Take a 50-question timed Building mock and score it against your target pass margin.
Categorize every miss as knowledge gap, misread, or calculation slip, and count each category.
Re-study only the knowledge-gap items and re-test them within 48 hours.
Condense the entire Building domain into a single two-page review sheet.
Your checkpoint
A scored 50-question Building mock with a categorized error tally and a completed two-page Building review sheet.
Plumbing
Map the Plumbing domain into a checklist of topic areas and rank them by the 50% share they carry.
Read the plumbing-fixtures, water-supply, and drainage material and write a one-page summary of each system in your own words.
Define 25 Plumbing-domain terms with one worked example apiece and add 40 tagged flashcards.
Trace a complete supply and drainage path for a simple building and label every component from memory.
Your checkpoint
A ranked Plumbing topic checklist, a 25-term glossary, 40 flashcards, and a labeled supply-and-drainage path diagram.
Plumbing
Work through at least 60 Plumbing-domain practice questions on fixtures, water heating, venting, and drainage, logging every miss with its root cause.
Rewrite each missed concept as a corrected rule statement of one or two sentences.
Practice 20 calculation-style Plumbing items (pipe sizing, fixture units, slope) under timed conditions.
Recite key Plumbing numeric thresholds from memory and flag any you cannot recall.
Your checkpoint
An error log of at least 60 attempted Plumbing questions with corrected rule statements, plus a scored 20-question calculation set.
Plumbing & Building
Drill the Plumbing subtopics below 70% accuracy until you reach 80% or better on a fresh set of 30 questions.
Re-test the weakest Building subtopics from week 4 with 25 mixed questions to confirm retention.
Answer 20 questions that combine Building and Plumbing constraints, such as fixture placement and penetration firestopping.
Condense the Plumbing domain into a single two-page review sheet.
Your checkpoint
A scored 30-question Plumbing re-test, a 25-question Building retention check, and a completed two-page Plumbing review sheet.
Building & Plumbing
Take two full-length timed mocks weighted 50/50 across both domains and score each against the pass margin.
Review only the misses from both mocks and re-test each within 48 hours.
Rehearse your two review sheets aloud until you can reproduce both from memory.
Finalize an exam-day plan covering timing per question, flag-and-return strategy, and reference materials allowed.
Your checkpoint
Two scored full-length mocks with all misses re-tested and a written exam-day timing plan.
Milestones
Week 4: Score at least 75% on the 50-question timed Building mock and show that no single Building subtopic falls below 60% accuracy.
Week 6: Complete the Plumbing error log with at least 60 questions attempted and reach 70% or better on the 20-question timed calculation set.
Week 8: Score at least 80% on both full-length 50/50 mocks, with every missed item re-tested and passed within 48 hours.
