PE Exam Prep: Free Study Plan and Practice Questions

This is free prep for the NCEES PE exam (U.S. engineering licensure). Do the 60-minute session below today, then follow the 12-week plan built around your exam's official specification.

Your first 60 minutes

Your first 60 minutes
MinutesDo thisYou're done when
0–10Name your exact exam (for example, "PE Civil: Transportation," not "PE Civil") and your target test date. Find it in the exam table. Note the date your exam's specification took effect and whether you'll test before or after a published change. Civil and PE Structural reference lists change for exams beginning April 2027.You've written down the exam, date, and spec version.
10–20Download your exam specification (the official topic list with question ranges) from the NCEES page in the exam table. Log in to MyNCEES for the NCEES reference handbook. Search the handbook for three formulas you already know. If your account isn't set up yet, skip ahead and come back.You can find a known formula in under a minute.
20–40Work Questions 9–10 on general exam rules, plus any technical questions below labeled for your exact exam. Civil: Structural candidates should also try Question 11; Power candidates, Question 12. Before you check any answer, write down your reasoning. For calculations, include what's being asked, your assumptions, the equation, and the units.Every attempt is on paper, reasoning included.
40–50Check your answers. For each miss, find the first wrong step and log it in the error log.Every miss or guess has a log entry with a cause.
50–60Put four study blocks for the coming week on your calendar, each with a topic and a task, such as "Tuesday 7–8 p.m.: three-phase power, five fresh problems."Four specific appointments exist.

Eligibility to sit is set by your state licensing board, not NCEES. If you haven't confirmed it yet, find your board in the NCEES board directory. Passing the exam is one part of licensure; it does not itself grant a license.

Free PE practice questions (12 original)

These are original, unofficial practice questions written by Castleport Test Prep, not NCEES exam questions. They're a warm-up across Civil, Mechanical, and Electrical Power, plus four questions on scoring, submission, and exam-specific reference rules. Twelve questions can't measure readiness for your full PE exam, so treat your result as feedback on these items only.

Work each one before you open the answer. Most PE exams also use formats these questions don't copy, such as multi-select, drag-and-drop, point-and-click, and fill-in-the-blank.

Question 1 · PE-C-01 · PE Civil: Structural — forces and load effects

A simply supported beam spans 24 ft and carries a uniformly distributed load of 1.5 kips/ft, including self-weight, over its full length. What is the maximum bending moment?

  • A. 54 kip-ft
  • B. 108 kip-ft
  • C. 216 kip-ft
  • D. 432 kip-ft
Answer and explanation

B. 108 kip-ft. Each support reaction is wL/2 = 1.5 × 24 / 2 = 18 kips. Cut the beam at midspan and sum moments on the left half: 18 × 12 − (1.5 × 12) × 6 = 216 − 108 = 108 kip-ft. That's the familiar wL²/8 = 1.5 × 576 / 8.

  • A (54) is wL²/16. Half the right moment.
  • C (216) takes the reaction times 12 ft but forgets the load sitting on that half of the beam.
  • D (432) is wL²/2, the cantilever formula. Wrong support condition.

The habit to build: check the supports before you reach for a formula.

Principle: static equilibrium, OpenStax University Physics Vol. 1, §12.1. Topic: PE Civil: Structural specification, knowledge area 2, Analysis of Structures–Forces and Load Effects.

Question 2 · PE-C-02 · PE Civil: Water Resources and Environmental — hydrology

A 12-acre commercial site has a runoff coefficient C = 0.80. For the design storm, uniform rainfall intensity for a duration equal to the time of concentration is 3.0 in/hr. Using the rational method, the peak runoff is closest to:

  • A. 2.4 cfs
  • B. 9.6 cfs
  • C. 28.8 cfs
  • D. 36.0 cfs
Answer and explanation

C. 28.8 cfs. Q = CIA = 0.80 × 3.0 × 12 = 28.8 cfs. In U.S. units, 1 acre-inch per hour is about 1.008 cfs, so the precise value is about 29.0 cfs. C is still the closest choice.

  • A (2.4) leaves out the area.
  • B (9.6) leaves out the rainfall intensity.
  • D (36.0) leaves out C, as if every drop of rain ran off.

The rational method gives a peak flow rate for small drainage areas. It doesn't give a runoff volume.

Principle: Iowa DOT Design Manual, Section 4A-5, the rational method. Topic: PE Civil: WRE specification, knowledge area 7, Hydrology; 7B, Runoff analysis.

Question 3 · PE-C-03 · PE Civil: Geotechnical — lateral earth pressure

A smooth, vertical 12-ft retaining wall holds level, dry, cohesionless backfill with a friction angle φ = 30° and unit weight γ = 120 pcf. There's no surcharge and no water. Assume the wall moves sufficiently away from the backfill to mobilize active pressure. Using Rankine theory, what is the total active force per foot of wall?

  • A. 2.88 kips/ft
  • B. 5.76 kips/ft
  • C. 8.64 kips/ft
  • D. 25.9 kips/ft
Answer and explanation

A. 2.88 kips/ft. Ka = tan²(45° − φ/2) = tan²(30°) = 1/3. The pressure diagram is a triangle, so Pa = ½ × Ka × γ × H² = 0.5 × (1/3) × 120 × 144 = 2,880 lb/ft. It acts H/3 = 4 ft above the base.

  • B (5.76) drops the ½. It's the base pressure times the height, not the triangle's area.
  • C (8.64) uses K = 1, treating the soil like a fluid.
  • D (25.9) uses Kp = 3, the passive case. Passive resistance is mobilized when the wall moves sufficiently into the soil; active pressure is mobilized as the wall moves away.

Principle: FHWA Geotechnical Engineering Circular No. 4, §4.4.2–4.4.4, printed pp. 36–38 and 41. Topic: PE Civil: Geotechnical specification, knowledge area 8, Retaining Structures (ASD or LRFD); 8A, Lateral earth pressure and load distribution.

Question 4 · PE-C-04 · PE Civil: Structural — construction safety

Under OSHA's construction fall-protection rule for unprotected sides and edges, 29 CFR 1926.501(b)(1), an employee on a walking/working surface must be protected from falling when the edge is at least how far above a lower level?

  • A. 4 ft
  • B. 6 ft
  • C. 10 ft
  • D. 15 ft
Answer and explanation

B. 6 ft. Section 1926.501(b)(1) sets the trigger at 6 feet (1.8 m). It requires a guardrail system, a safety net system, or a personal fall arrest system.

The other heights show up in other rules and situations, which is exactly why you go to the named paragraph instead of answering from memory. The listed 29 CFR subparts are among the references supplied on PE Civil: Structural.

Source: 29 CFR 1926.501(b)(1), eCFR. Topic: PE Civil: Structural specification, knowledge area 3E, Safety, and its design-standards list.

Question 5 · PE-M-01 · PE Mechanical: Thermal and Fluid Systems — pumps

A pump moves 0.05 m³/s of water (ρ = 1,000 kg/m³) against a total head of 40 m. Pump efficiency is 75%. What shaft (input) power is required?

  • A. 2.67 kW
  • B. 14.7 kW
  • C. 19.6 kW
  • D. 26.2 kW
Answer and explanation

D. 26.2 kW. First find the hydraulic power, the power the pump actually delivers to the water: ρgQH = 1,000 × 9.81 × 0.05 × 40 = 19,620 W ≈ 19.6 kW. Shaft power = hydraulic power ÷ efficiency = 19.62 / 0.75 = 26.16 ≈ 26.2 kW.

  • C (19.6) stops at hydraulic power.
  • B (14.7) multiplies by efficiency instead of dividing. At 75% efficiency, input power has to exceed hydraulic output.
  • A (2.67) leaves out g, so the "power" isn't in watts at all.

Principle: Hydraulic Institute, Pump System Certification formula reference sheet, pp. 5–6, pump output and input power. Topic: PE Mechanical: TFS specification, knowledge area 2C, Pumps and Fans.

Question 6 · PE-M-02 · PE Mechanical: Thermal and Fluid Systems — energy balance

At steady state, liquid water flows through a heater at 2.4 kg/s and warms from 18°C to 35°C. Use a constant specific heat of 4.18 kJ/(kg·K). The water stays liquid. Ignore kinetic and potential energy changes and pressure effects, and assume no shaft work. What is the heat-transfer rate into the water?

  • A. 2.84 kW
  • B. 170.5 kW
  • C. 351 kW
  • D. 3,091 kW
Answer and explanation

B. 170.5 kW. Q̇ = ṁ × cp × ΔT = 2.4 × 4.18 × (35 − 18) = 170.544 kJ/s ≈ 170.5 kW.

A rise of 17°C is the same as a rise of 17 K, so you don't convert to absolute temperature for a temperature difference.

  • A (2.84) divides by 60, as if the flow were in kg/min. It's already in kg/s.
  • C (351) uses the outlet temperature instead of the temperature change.
  • D (3,091) uses the outlet temperature in kelvin.

This shortcut only works without a phase change. If the water boiled, you'd need enthalpies from steam tables.

Principle: DOE Fundamentals Handbook, Thermodynamics, Heat Transfer, and Fluid Flow, Vol. 1, Module HT-01, printed p. 63, Example 2 (no-phase-change condition). Topic: PE Mechanical: TFS specification, knowledge area 1B, Thermodynamic Principles.

Question 7 · PE-P-01 · PE Electrical and Computer: Power — three-phase circuits

A balanced, sinusoidal three-phase load draws 100 kW at 0.80 power factor lagging from a 480-V RMS line-to-line supply. What is the RMS line current, approximately?

  • A. 120 A
  • B. 150 A
  • C. 208 A
  • D. 260 A
Answer and explanation

B. 150 A. Real power in a balanced three-phase load is P = √3 × V(line-line) × I(line) × power factor. So I = 100,000 / (1.732 × 480 × 0.80) ≈ 150 A.

  • A (120) leaves out power factor. That's the current for 100 kVA, not 100 kW at 0.80 power factor.
  • C (208) uses a single-phase formula with no power factor (100,000 / 480).
  • D (260) leaves out √3.

Principle: DOE Fundamentals Handbook, Electrical Science, Vol. 3, Module ES-09, printed pp. 20–21, three-phase current from real power. Topic: PE Power specification, knowledge area 4A, Three-phase circuits.

Question 8 · PE-P-02 · PE Electrical and Computer: Power — power factor correction

A plant load is 100 kW at 0.80 power factor lagging. Assume sinusoidal operation, the load's real power remains 100 kW, and capacitor and feeder losses are negligible. How much capacitive reactive power is needed to raise the power factor to 0.95 lagging?

  • A. 32.9 kVAR
  • B. 42.1 kVAR
  • C. 60.0 kVAR
  • D. 75.0 kVAR
Answer and explanation

B. 42.1 kVAR. Capacitor kVAR = P × (tan θ1 − tan θ2).

  • At 0.80 power factor, θ1 = 36.87°, so tan θ1 = 0.750.
  • At 0.95 power factor, θ2 = 18.19°, so tan θ2 = 0.329.
  • 100 × (0.750 − 0.329) ≈ 42.1 kVAR.

Why the other choices are wrong:

  • D (75.0) removes all the reactive power, correcting to unity power factor.
  • A (32.9) is the reactive power that remains after correction.
  • C (60.0) computes P sin θ1 = 60 kVAR instead of P(tan θ1 − tan θ2).

Under these assumptions, the load still draws 100 kW; the capacitors reduce the reactive power supplied by the source.

Principle: WBDG / DoD TSEWG TP-2, Capacitors for Power Factor Correction, p. 2, "Determining Capacitor Size." Topic: PE Power specification, knowledge area 8C, Power factor correction.

Question 9 · PE-X-01 · NCEES alternative-item scoring

A "multiple correct" question has three correct options. You select two of them and no wrong ones. How is the question scored?

  • A. Full credit
  • B. Two-thirds credit
  • C. No credit
  • D. It depends on the question's difficulty
Answer and explanation

C. No credit. NCEES scores every question, including alternative item types like multi-select, as simply correct or incorrect. There's no partial credit. Read multi-select stems slowly and judge each option on its own.

Source: NCEES computer-based testing page, "Alternative Item Types"; NCEES Examinee Guide, May 2026, p. 11.

Question 10 · PE-X-02 · All PE exams — submitting a question group

Your PE exam prompts you to review and submit a set of questions before your optional break. After you submit, can you go back to those questions?

  • A. Yes, any time before the clock runs out
  • B. Yes, but only during the break
  • C. No
  • D. Only the ones you flagged
Answer and explanation

C. No. Once you submit the first section, you lose access to those questions. Before you submit, answer every flagged question. Unanswered scored questions earn no credit, and NCEES doesn't deduct points for wrong answers, so a guess can only help.

Source: NCEES Examinee Guide, May 2026, pp. 11 and 14.

Question 11 · PE-X-03 · PE Civil — code editions

You're scheduled to take PE Civil: Structural in May 2027. Which edition of ACI 318 will be supplied on your exam?

  • A. ACI 318-11
  • B. ACI 318-14
  • C. ACI 318-19 (2022)
  • D. Whichever edition your state has adopted
Answer and explanation

C. ACI 318-19 (2022). The Civil: Structural design-standards list effective beginning April 2027 specifies ACI 318, 2019 (2022). NCEES scores code-based answers against the edition on that list. Its specification says solutions based on other standards won't receive credit.

  • B is the edition on the list used before April 2027.
  • D does not determine the references supplied on this exam; the dated NCEES list does.

Source: PE Civil: Structural design standards effective April 2027, design-standards page.

Question 12 · PE-X-04 · PE Power — code editions

Under the PE Electrical and Computer: Power specification effective with the October 2025 exam, which edition of the National Electrical Code (NFPA 70) is supplied?

  • A. 2017
  • B. 2020
  • C. 2023
  • D. The edition adopted where you work
Answer and explanation

B. 2020. The Power codes list specifies NFPA 70-2020. Practice your table lookups in that edition, even if your jurisdiction has already adopted a newer one.

Source: PE Power specification, codes and standards page.

After the set: Log every miss, and every lucky guess, in the error log. Then retry the method on a fresh problem in a later session. Getting the same question right a second time does not show whether you can apply the method to a fresh problem.

The 80-question exams use a 9-hour appointment and the 85-question exams a 9.5-hour appointment. The extra time covers a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break. The fee is $400 per attempt, paid to NCEES, and some boards add their own application fee. Single-day exams are first-come for seats, so book early. (Examinee Guide, May 2026, pp. 3 and 16)

PE Structural is a different exam from PE Civil: Structural. It has four sections: vertical breadth, vertical depth, lateral breadth, and lateral depth.

  • Breadth sections: 55 questions in 5.5 hours, offered year-round.
  • Depth sections: offered twice a year. Through the October 2026 dates, each has 60 questions in 6 hours, all alternative item types. Beginning April 2027, each has 48 questions in 6 hours and adds multiple-choice items.
  • Fees and results: each section costs $350. Depth results take 10–13 weeks.
  • Acceptance: not every jurisdiction accepts PE Structural as its PE exam, so check with your board.

See NCEES PE Structural. The 12-week plan below is written for single-sitting exams. For PE Structural, use the same method but give each section its own topic map and schedule.

Check two dates: your topics and your references

For exams that supply design standards, check two parts of the specification that can change on different schedules:

  • the topic list, with question ranges
  • the list of design standards and codes supplied during the exam

The Civil: Structural topics didn't change for 2027, but nearly every reference edition did:

Your 12-week PE study plan

Assumptions: about 10 focused hours a week (120 hours total), your exam already chosen, and a full-time job. A typical week might be four 1-hour weeknight sessions plus two 3-hour weekend blocks. This template is for one single-sitting exam; give each PE Structural section its own topic map and schedule. This is our editorial plan, not an NCEES requirement. No number of hours guarantees a pass.

In Week 1, split your whole specification into four workload bundles, A through D. Group topics that build on each other. Keep every official topic on your list, even ones you think you know.

Decide what to study first

Give every topic in your specification one of three statuses:

  • Not sampled: you haven't tried problems yet. Unknown isn't the same as strong.
  • Needs repair: you've missed problems here, and you know the first wrong step.
  • Demonstrated on these problems: you solved fresh problems correctly without hints. This covers those problems, not the whole area.

Then put first the topics with a bigger official question range and a "Not sampled" or "Needs repair" status. The ranges come straight from NCEES.

For example, the Civil: Structural specification gives Design and Details of Structures–Component Design and Detailing 26–39 questions and Temporary Structures and Other Topics 5–8 questions (spec, p. 2). If you're shaky on both, the first one deserves far more of your time. Use the ranges to set priorities. They're not an exact formula for hours.

Match the fix to the error:

  • Unit slip: practice conversions, then do a fresh problem.
  • Wrong model: go back to the concept and its assumptions before doing more problems.
  • Slow lookup: run reference drills.

Copy this record and keep it with your notes:

Study hours I can really give per week: ______
Next topic and session date: ______

Have more or less time?

  • Six hours a week: the same 120-hour plan takes about 20 weeks. Stretch each week's work across about 1.7 calendar weeks.
  • Fifteen hours a week: about 8 weeks. Redistribute the same 120 hours across eight 15-hour weeks, preserving the task order, review time, and full rehearsal.
  • Missed a week: don't quietly drop a weak topic. Move the unfinished tasks forward where you can see them, and protect review time and fresh-problem checks.
  • Calendar no longer fits: reassess your test date. You can attempt an exam once per testing window and no more than three times in 12 months (Examinee Guide, p. 5). Single-day exams have only one date a year, so a moved date can mean a long wait.
  • Low-energy day: do 20 minutes. Spend 5 recalling a setup, 10 working one problem step, and 5 logging the next action. It keeps the streak alive. It doesn't replace the longer sessions.

Turn mistakes into your next session

A practice score tells you that you missed something. The error log tells you why, and the why is what you study next.

Example, using Question 7:

  • First answer: A (120 A).
  • First wrong step: used P = √3 × V × I and forgot the power factor, so the 100 kW was treated as 100 kVA.
  • Cause: concept, mixing up real and apparent power.
  • Fix: label kW and kVA before calculating, and include power factor whenever real power is given.
  • Next action: work a fresh three-phase problem that asks for both real and apparent power.
  • Retry: leave this blank until you've actually done it.

Log lucky guesses too. A correct answer you couldn't explain is a miss waiting to happen.

Practice with the references you'll actually have

The PE is closed book. On exam day you get the NCEES reference handbook on screen, plus any design standards listed in your specification's reference section, and nothing else (Examinee Guide, p. 10). Older advice about tabbing your own books or packing a box of manuals is out of date for the computer-based exam.

A five-minute lookup drill:

  1. Pick a problem.
  2. Name the relationship you need in plain words, such as "pump efficiency" or "three-phase power."
  3. Search the handbook for that phrase.
  4. Check the variable definitions and units next to the equation.
  5. Apply it.
  6. Write down the search words that worked.

Do this until the handbook feels like a tool you know, not a stranger.

Exam-day rules that change how you practice:

  • Search box, not Ctrl+F. The exam's PDF viewer has its own search box on the left, and Ctrl+F doesn't work. Civil and Power design standards open one chapter at a time. So practice finding things by chapter and keyword, not by a desktop shortcut (Examinee Guide, p. 10; Civil: Structural spec, standards page). NCEES posts short video tutorials on the exam's reference viewer.
  • One approved calculator. For 2026 exams, the approved models are any Casio fx-115 or fx-991 model, the HP 33s and HP 35s only, and any TI-30X or TI-36X model. An on-screen TI-30XS is also available. Practice on the exact calculator you'll bring. NCEES reviews the list every year (NCEES 2026 calculator policy, p. 1; Examinee Guide, p. 8).
  • Markers, not pencils. You get two reusable booklets and three markers (Examinee Guide, p. 9). Do some practice on a whiteboard or laminated sheet so it isn't new on exam day.
  • About 6 minutes per question. 480 minutes ÷ 80 questions = 6.0, and 510 ÷ 85 is also 6.0. That's an average, not a per-question limit, and it doesn't include the scheduled break.
  • Submitting a question group is final. Once you submit a group, you can't return. Clear your flags first (Examinee Guide, p. 11).
  • Unscheduled breaks run on your time. The clock keeps going, and you can't leave the building (Examinee Guide, p. 12).
  • Arrive 30 minutes early. Your first and last names on the appointment confirmation and your ID must match (Examinee Guide, pp. 8–9).

How the PE is scored, and what a practice score means

NCEES counts your correct answers and doesn't take points off for wrong ones. It converts that count to a scaled score and compares it with a passing standard set by subject-matter experts. NCEES doesn't publish the passing score, so "you need 70%" claims you'll find online aren't based on anything official.

Each exam also includes unscored pretest questions that look like every other question. Answer everything.

Results usually arrive in 7–10 days as pass or fail. PE Structural depth results take 10–13 weeks. If you don't pass, you get a diagnostic report. It compares your performance in each knowledge area, on a 0–15 scale, with the average of passing examinees. (Examinee Guide, pp. 11, 14, and 20)

A practice score describes how you did on those questions, under those conditions. It's useful for finding weak spots. It isn't a pass prediction. Retaking? Start your plan from the diagnostic report: weigh both the performance gap and the number of questions in each area. Then confirm each fix on fresh problems.

PE pass rates

These are NCEES-reported rates for the highest-volume year-round PE exams, from the table NCEES updated in July 2026. The cohort is January–June 2026 examinees under NCEES member-board jurisdictions.

NCEES reports year-round exams by half-year group. These rates describe groups of examinees, not your personal chances. The full table, including single-day exams, is on any NCEES PE discipline page. PE Structural rates are on its own page.

In every exam listed, repeat takers passed at a lower rate than first-time takers. Our takeaway: prepare fully for the first attempt rather than planning on a retake.

Quick answers

Do I have to pass the FE first? Most candidates take the FE before the PE, but your state board decides eligibility. Check the board directory. If your board requires the FE and you haven't taken it yet, start with FE exam prep.

Do I need four years of experience to sit? NCEES designs the PE for engineers with at least four years of post-college experience. Whether you can sit earlier is your board's rule, not NCEES's (NCEES PE exam).

What does it cost?

  • NCEES fee: $400 per attempt, except PE Structural, which is $350 per section.
  • Board fee: your board may charge its own application fee.
  • Pearson fees: $50 to reschedule or cancel an appointment. Reschedule at least 48 hours ahead; cancel more than 48 hours ahead.

How soon can I retake it? Once per testing window (January–March, April–June, July–September, October–December), and no more than three times in any 12 months. Some boards are stricter. Your next attempt must also fall on a date when that exam is offered; annual exams and twice-yearly PE Structural depth sections follow their published dates. See NCEES retake rules.

Can I get testing accommodations? Yes, but you have to request them during registration. See NCEES reasonable accommodations.

Do I need a prep course? No. A course is optional. Whatever you use, make sure it matches your current specification and the reference editions for your test date.

Is this the PE exam for physical education teachers? No. This page covers the engineering PE exam from NCEES.
