BOABC Level 2 study plan

BOABC Level 2 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

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.

Week 2

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.

Week 3

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.

Week 4

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.

Week 5

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.

Week 6

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.

Week 7

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.

Week 8

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.
