9.5 Last-Minute Exam Tips
Key Takeaways
- Memorize standard versions and thresholds: ASHRAE 90.1-2016 (energy), 62.1-2016 (ventilation), 55-2017 (thermal comfort); IES TM-30 with sDA ≥55% and ASE <10% (daylight); CDPH v1.2 (VOC); MERV 13 (filtration).
- Memorize the key LEED numbers: 40/50/60/80 certification thresholds, 30% open space, 22,000 sf/acre density, 75% C&D waste diversion, 25% recycled content for Exemplary Performance MR, 95th-percentile rainwater event.
- Allocate roughly 60 seconds per question on the 100-question, 2-hour exam — flag harder questions on the first pass and return to them rather than getting stuck.
- Beware absolute words like 'always', 'never', 'only', 'must', 'all' — they often signal a wrong answer because LEED has many conditional rules and exceptions.
- Bring a valid government-issued photo ID; scratch paper and pencils (or whiteboard for online proctored) are provided — no personal materials are allowed in the test area.

High-Yield Numbers You Must Memorize
The LEED AP BD+C exam reuses a short list of standards, thresholds, and percentages across many questions. Lock these in before exam day.
Referenced Standards (current LEED v4.1)
| Category | Standard | What It Sets |
|---|---|---|
| Energy baseline | ASHRAE 90.1-2016, Appendix G | Energy modeling baseline for EA Optimize Energy Performance |
| Ventilation | ASHRAE 62.1-2016 | Minimum outdoor air for indoor air quality |
| Thermal comfort | ASHRAE 55-2017 | Acceptable indoor temperature/humidity range |
| Lighting quality | IES TM-30 | Color rendering metric (replaces simple CRI) |
| Daylight | sDA ≥55%, ASE <10% | Spatial Daylight Autonomy / Annual Sunlight Exposure thresholds |
| Water fixtures | EPA WaterSense | Maximum flow/flush for showers, faucets, water closets |
| Indoor VOC | CDPH v1.2 (California Section 01350) | Emissions limits for paints, adhesives, flooring, ceilings |
| Wood sourcing | FSC (Forest Stewardship Council) chain-of-custody | Sustainable forest products |
| Material disclosure | EPD (Environmental Product Declaration) / HPD (Health Product Declaration) | Transparency for MR Building Product Disclosure |
| Filtration | MERV 13 | Particulate filter minimum for EQ Enhanced IAQ Strategies |
Key Percentage and Threshold Numbers
| Topic | Threshold |
|---|---|
| Certification levels | Certified 40 / Silver 50 / Gold 60 / Platinum 80 (out of 110) |
| Total available points | 100 base + 6 IN + 4 RP = 110 |
| Open Space | 30% of site as open space (60% for Exemplary Performance) |
| Surrounding Density | 22,000 sf of building area per acre within ½-mile radius |
| C&D Waste Diversion | 75% diversion (Exemplary at ~95%) |
| Rainwater Management | 95th-percentile rainfall event managed on site |
| Indoor Water Reduction | 25% mandatory (prerequisite) / up to 50% reduction for full points |
| Outdoor Water Reduction | 50% reduction baseline (prerequisite); 100% for full points |
| Energy Reduction | Up to 24% for top tier in EA Optimize Energy Performance (Exemplary doubles to 48–50%) |
| Heat Island — non-roof | SR ≥0.33 at installation, 0.28 after 3 years (or SRI 29/15) |
| Heat Island — roof | SRI 82 for low-slope, 39 for steep-slope |
| Daylight | sDA ≥55% (good); sDA ≥75% (best); ASE <10% to limit glare |
| Acoustic — Schools | Background noise ≤35 dBA in core learning spaces |
Recognizing Question Patterns
LEED AP BD+C questions tend to fall into four shapes:
- Definition questions — "What is a Credit Interpretation Ruling?" → Answer is the textbook definition.
- Numeric questions — "What is the maximum SRI required for a low-slope roof to meet the Heat Island credit?" → Memorized number wins.
- Scenario questions — "A project team discovers... what is their BEST next step?" → Pick the answer that follows GBCI process correctly.
- Synergy questions — "Which credit MOST DIRECTLY supports this one?" → Look for the category pair you have seen repeated (e.g., daylight + lighting controls, rainwater + open space).
Test-Taking Strategies
Time Management
- The exam is 100 questions in 2 hours — that is 72 seconds per question on average, often rounded to 60 seconds as a target with buffer time.
- Flag and skip questions you cannot answer in 90 seconds; return to them after the first pass.
- Plan to leave 15 minutes at the end for flagged questions and a final scan.
Eliminating Wrong Answers
- Eliminate clearly wrong options first — many questions have one absurd answer and one almost-right distractor.
- Watch for absolute words: 'always', 'never', 'only', 'must', 'all', 'every'. LEED rarely operates in absolutes because credits include exceptions, alternate paths, and thresholds.
- Watch for answer pairs — when two options are mirror opposites, one of them is usually correct.
Reading the Question Fully
- Read every word — qualifiers like 'BEST', 'MOST', 'EXCEPT', 'NOT', 'FIRST' change the right answer.
- Re-read the question after picking an answer if you have time.
- The stem and answers must agree — do not pick an answer because the option itself is true; pick the one that answers the specific question.
Guessing Strategy
- There is no penalty for wrong answers — answer every question.
- If forced to guess, eliminate two clearly wrong options first; the remaining two give you a 50% shot rather than 25%.
What to Bring to the Test
Allowed
- Two forms of ID — one government-issued photo ID (driver's license, passport) and one secondary ID with matching name
- A confirmation email or appointment number (Prometric or online proctored)
Provided at the Test Center
- Scratch paper and pencils (in-person testing centers)
- A whiteboard and marker (online proctored testing)
- A calculator is built into the exam interface — no personal calculators allowed
NOT Allowed
- Personal notes, the LEED Reference Guide, or any printed material
- Phones, smartwatches, fitness trackers, or other electronics
- Food, beverages, hats, jackets, or bags inside the test area (storage lockers provided)
Online Proctoring Specifics
- A clean, quiet, private room is required — no other people, no second monitors, no posters with text
- The proctor will scan the room via webcam before the exam begins
- Bathroom breaks are not allowed during the 2-hour LEED AP BD+C exam
Final 48-Hour Plan
| When | Do |
|---|---|
| 2 days before | Review the high-yield numbers table above, run a final timed practice exam |
| 1 day before | Light review only — quizlet of standards versions, a walk, full meal, early sleep |
| Morning of | Eat protein, hydrate moderately, arrive 30 minutes early, bring both IDs |
| During exam | First pass at 60 sec/Q, flag the hard ones, then second pass, then 15-min review |
| After exam | Score is shown immediately on screen; passing score is 170 of 200 scaled |
A reminder: the BD+C exam is 170 of 200 scaled score to pass — that translates to roughly 70–75% correct, depending on item difficulty weighting.
