The honest answer: the Virginia business exams are moderately hard, not because the concepts are deep but because the test is wide, number-heavy, and timed at about 2 minutes per question. Experienced builders who prepare properly pass; experienced builders who walk in cold fail. Here is a realistic assessment of the difficulty, the passing lines, and what separates passers from failers.
The passing lines
Each of the three portions sets its own bar, and you must clear every portion your class requires:
- Virginia Portion: 18 of 24 (75%).
- General Portion: 35 of 50 (70%).
- Advanced Portion: 17 of 24 (about 71%).
A 75% bar on a 24-question test is tighter than it looks: miss 7 and you fail the Virginia Portion. Five to 10 unscored experimental questions may be mixed in, and they do not count, so do not burn time on a question that feels alien. Scores are valid for 1 year; if every required portion is not passed within that year, the entire examination must be retaken. For the full format and rules, start there.
Why "open book" fools people
The exam lets you bring your references, and many candidates hear that as "easy." The references are large, the time is short, and the questions target figures: 90 days or 120 days, $30,000 or $100,000, 7 days or 60 days. A candidate with an untabbed, unmarked NASCLA book spends the whole exam hunting. A candidate with a tabbing map and highlighted numbers finishes with minutes to spare. Open book tests retrieval speed, not recall, and retrieval speed is a skill you can train.
The hardest topics
These are the areas where prepared candidates score and unprepared ones bleed:
- Lien deadlines. Virginia's memorandum rule runs 90 days from the last day of the month of last work, capped at 90 days after completion; enforcement runs 6 months after recording or 60 days after completion, whichever is later; and the 150-day rule lurks underneath. Three overlapping clocks is exactly the kind of material this exam tests.
- VPPA prompt payment. Seven days prime-to-sub after public funds, 60 days when the prime has not been paid, 1% per month default interest, pay-if-paid void on public projects, 30 days for state agencies, 45 days for localities. The wrong answers mix up which clock goes with which party.
- Taxes. The contractor-as-consumer rule, the separately-stated-labor exemption versus lump-sum taxation, and per-location registration. Field experience teaches none of this.
- The designated-employee conflict. The statute says 90 days, the regulation says 120 days, and the exam knows it is unsettled. Candidates who learned only one number get this wrong.
- Stale figures. Nearly every third-party prep book still prints the pre-2025 Class A thresholds ($120,000/$750,000) and the old Recovery Fund limits ($20,000/$40,000). Studying outdated material is the most common cause of failure on the Virginia-specific portion.
What failers have in common
Talk to anyone who failed and the story rhymes: they brought an unmarked book, they studied 2024 materials, they ran out of time on the General Portion, or they treated the business exam like a formality after decades in the field. The exam does not care how good a builder you are; it tests whether you can run a contracting business inside Virginia law. That is a different subject.
Class A has the heaviest lift because of the Advanced Portion: 24 questions going deeper on estimating, contracts, labor law, financial management, and taxes. But the fallback exists: Class A candidates who pass the Virginia and General portions but not Advanced within the year may apply for Class B and have PSI forward their scores.
What passers do differently
- They tab and highlight the NASCLA Virginia 11th Edition before exam day (permanent tabs only, no writing added).
- They drill the figures until the numbers are reflexes: 18/24, 35/50, 17/24; $150,000/$1,000,000; $30,000/$100,000; 90 days; 7/30/45 days; 6 feet; 5 feet.
- They run at least one timed pass at 2 minutes per question with the book open.
- They use the two-pass method: answer what they know, flag the rest, and work flagged questions in payoff order.
No one can promise you a passing score, and you should distrust anyone who does. But the exam is entirely passable with structured preparation: it rewards the candidate who treats it as its own subject, builds the retrieval system, and learns the 2025 law.
