Practice exam review and test-day strategy

Three weeks before her exam date, Keisha took her first full timed practice test at the kitchen table on a Saturday morning: one hundred questions, six hours, her tabbed code book, the NFPA 72 standard, the business guide and the licensing law. She finished with forty minutes left and scored 66. "Good," Glenn said when she told him. "Now you know where the points are." This lesson pulls the course together. It reviews an eight-week study plan, walks through a mixed practice set that touches every earlier lesson, explains a two-pass method and a pacing plan for a six-hour open-book exam, and covers what to do the week before, the morning of, and the day after.

How the exam rewards preparation

Lesson 4 described the exam for the limited, intermediate and unlimited classifications: one hundred questions in six hours, computer-based at PSI, open book, with a passing score of 70. The open-book format changes what preparation means. Candidates do not need to memorize the code; they need to find things in it quickly and read what they find accurately. They also need enough command of the licensing law, the lien law and the business topics to answer without searching, because those questions can eat time when a candidate has to hunt for them in an unfamiliar book. A candidate who knows where every major article sits and has practiced common calculations until they are routine has time left over for the hard questions.

The eight-week plan

Keisha's plan, which this course has followed, ran for eight weeks before her March exam. Week one was setup: reading the board's candidate information, confirming the current reference list, buying the exact editions, and tabbing the books within the permitted rules. Week two covered North Carolina law: Article 4 of Chapter 87, the board's rules, classifications, qualified individual duties and penalties. Week three was the business guide: contracts, liens, bonds, insurance, payroll, taxes and safety recordkeeping. Week four was calculations: load calculations, conductor sizing and ampacity adjustment, box and conduit fill, voltage drop, motor circuits and service sizing. Week five was code lookup drills against a timer. Week six covered NFPA 72 for fire alarm questions. Week seven was full timed practice, and week eight went to weak areas.

The plan's order is deliberate. The law and business material is learned early because it is the part that can be answered from memory, which saves time on exam day. The calculation and lookup work comes in the middle, when the tabs are in place. Full timed practice comes late enough to measure real readiness and early enough to leave a week to fix what it reveals.

A mixed review set

The questions below sample each part of the course. Work through them with the references closed for the law and business items and open for the code items, and note how long each takes.

# Practice pacing for a 100-question, 6-hour exam
from datetime import datetime, timedelta
start = datetime(2026, 3, 6, 8, 30)
minutes = 6 * 60
per_q = minutes / 100
print(f"average per question: {per_q:.1f} minutes")
for done in (25, 50, 75, 100):
    t = start + timedelta(minutes=done * per_q)
    print(f"question {done:>3} by {t:%H:%M}")

average per question: 3.6 minutes
question  25 by 10:00
question  50 by 11:30
question  75 by 13:00
question 100 by 14:30

The two-pass method

On a long open-book exam, the biggest risk is spending twenty minutes on one hard question while easy questions wait at the end. The two-pass method avoids that. On the first pass, the candidate answers every question that can be answered quickly from memory or with a short lookup, and marks any question that needs a long search or a multi-step calculation. On the second pass, the candidate works through the marked questions in order of expected payoff. The computer-based format lets candidates mark and return to questions, and candidates should confirm how the marking feature works in the tutorial at the start of the session.

A useful rule for the first pass is two minutes: if a question is not answered or clearly on its way after two minutes, mark it and move on. The average available time is 3.6 minutes per question, so a first pass that averages two minutes on the questions it answers leaves a large block of time for the marked ones. Never leave a question blank at the end; an unanswered question is always wrong, and a guess has a chance.

Reading questions carefully

Many wrong answers on licensing exams come from misreading, not from not knowing. Read the last line of the question first to see what is being asked, then read the whole question. Watch for words such as minimum, maximum, except, not and shall, and for units such as feet versus inches or volts versus volt-amperes. When a question gives a lot of detail, some of it may be there only to distract. When two answers look right, the question usually turns on one specific word. For code questions, read the whole section, including exceptions, before choosing; an exception often changes the answer.

Using the references efficiently

Tabs help only if they are used. In practice sessions, keep a list of every lookup that took more than a minute and decide whether a new tab or a better index habit would fix it. Use the code index for unfamiliar terms and the table of contents for article-level navigation. Keep the business guide and the licensing law tabbed by topic, such as liens, bonds, workers' compensation, payroll and recordkeeping, so a business question is a quick look rather than a search. Confirm in the candidate information which tabbing and highlighting are allowed, because references that do not meet the rules can be refused at check-in.

The week before

In the final week, the goal is confidence, not new material. Take one last timed section to confirm pacing, review the error log from practice tests, and reread the summaries of the law and business lessons. Confirm the PSI appointment, the test center address and parking, the arrival time and the ID requirements: two forms of identification, one of them a valid government-issued photo ID, with names matching the registration. Check that the references are the exact editions on the board's list and that tabs meet the rules. Plan the drive, and for a morning appointment, plan to arrive early enough to check in calmly.

Test day

On test day, eat a real breakfast, bring water and a snack for the break if the center allows it, and leave the phone in the car or the locker the center provides. At check-in, staff will verify identification and inspect the references. Use the tutorial to learn the navigation and marking tools before the clock starts. Once the exam starts, follow the pacing plan, take a short break if the rules allow one, and keep moving. A hard run of questions is normal and says nothing about the final score.

Keisha's exam at the PSI center in Greensboro started at 8:30. She marked twenty-two questions on the first pass, finished it shortly after the three-hour mark, worked the marked questions until about 2:00, and spent the last twenty minutes checking her guesses. Her score report appeared on the screen when she submitted: 78.

If the score falls short

A candidate who does not pass sees the score immediately and can use it to plan. The board offers an exam review session for a fee, held as a group session at the board office, which lets candidates see the areas they missed. A retake requires a new application and fee and a waiting period that the board's examination page describes in terms of about three months, so candidates should confirm the current rule. A candidate may sit for a different classification without that wait. The best response to a failed attempt is the same as the best response to a weak practice score: find where the points were lost and work on those areas.

Darnell, a friend of Keisha's from her apprenticeship class, failed his first attempt at the intermediate exam by four points. His review showed that he had lost most of his points on box fill and motor calculations and on business questions about payroll records. He spent the waiting period on those three areas, took two more timed practice tests, and passed his second attempt with a 75.

After passing

Passing the exam is one step in licensing, not the last. The board's records show the passing score, and the company completes the remaining licensing steps described in earlier lessons, including the application for the license, the fee, the qualified individual listing and, for intermediate and unlimited, the statement of bonding ability. Insurance certificates, workers' compensation coverage and the license tracker all need updating. Keisha's first act as qualified individual was to sit down with Ray and update the company's license file, the permit accounts and the renewal calendar, which is where this course began.
