What is SteamTicket, and what isn't it?

What SteamTicket is, and what it isn't

SteamTicket is:

  • Practice questions for your power engineering exam, organised by unit, with an explanation for each answer.
  • Timed mock exams for the standard SOPEEC multiple-choice papers: 100 questions in 3 hours, marked against the 65% pass mark. 313A uses 125 questions in 4 hours, with a 70% pass mark. 1st Class practice on papers A1 to A4 and B1 to B3 is multiple choice on the syllabus and does not match the long-answer paper.
  • A way to test yourself. SMART Quiz brings back the questions you miss, and your progress shows which units need more work.
  • Made by Jax & Noah Studios Inc., an independent Canadian company.

SteamTicket isn’t:

  • A textbook or a course. You learn the material from the free NAIT, SAIT and BCIT power engineering textbooks (CC BY-NC-SA) or your course materials. The free textbooks for every class are listed here. See the free textbooks
  • Affiliated with or endorsed by SOPEEC, ABSA, TSSA, Technical Safety BC or any regulator, or by NAIT, SAIT or BCIT.
  • A copy of the real exam. Every question is original, written to the public syllabus.
  • A promise of a pass. It shows you where you stand, so you can focus your study.

Your accepted course teaches it: we stick it

SteamTicket is not an ABSA-accepted course and we say so plainly. If you’re already in an accepted 4th Class program, this is the layer that turns course knowledge into exam marks: 596 questions keyed to every AB-054 objective, unlimited 100-question mocks in the real 3-hour format, and a worked explanation on every question.

$79 once: not every two weeks, not per year

Lifetime access for one payment. Compare: $40 every 2 weeks per paper (PE Practice) or $99 per paper per year (Full Steam Ahead). The longer your ticket takes, the wider the gap.

Write the paper, not the course

The SMART Quiz starts every session with your weakest units and re-asks what you miss. Your free sample ends with a weak-area readout, so you know exactly what to fix before exam day.

Competitor rates are public list prices checked 5 September 2026, confirm current pricing on their sites.

Those two rates are not the whole set. 4th Class power engineering practice exams compared and the compare hub keep the wider checked pages, including where another tool is the better fit.

The 4A exam format

The 4th Class certificate has two papers, Part A (4A) and Part B (4B), and you write them separately. SteamTicket’s 4A mocks use the real format (100 questions, 3 hours, 65% to pass). Real exam questions are worded differently, so study every unit, not just the mocks.

4A sample questions, explained

6 questions from our free public 4A sample, with the answer, a worked explanation, and why each other option is not the answer. They are original exam-style questions written to the public syllabus, not questions from a real exam. Print 10 free 4A questions.

1. A body travels a distance of 1000 m in 65 seconds at a constant rate. What is its average velocity?

  • A. 15.4 m/s
  • B. 18.2 m/s
  • C. 65.0 m/s
  • D. 12.5 m/s
Show the answer and explanation

Answer: A. Average velocity equals displacement divided by time: 1000 m ÷ 65 s ≈ 15.38 m/s, which rounds to 15.4 m/s. The choice of 65.0 m/s is a common error in which the student reads the time value (65 s) directly as a speed without performing the division.

Why the other options are not the answer

  • B. 18.2 m/s would mean 1000 m in about 55 s, not 65 s.
  • C. 65.0 m/s reads the time (65 s) as the speed without dividing.
  • D. 12.5 m/s would mean 1000 m in 80 s, not 65 s.

2. A chain drive uses a 300 mm diameter drive sprocket and a 1000 mm diameter driven sprocket. If the drive shaft turns at 890 rev/min, what is the rotational speed of the driven shaft?

  • A. 595 rev/min
  • B. 267 rev/min
  • C. 2967 rev/min
  • D. 445 rev/min
Show the answer and explanation

Answer: B. Chain drive speed ratio follows the same inverse-diameter rule as gear drives: N_driven = N_driver × (D_driver / D_driven) = 890 × (300/1000) = 267 rev/min. The driven sprocket is larger, so it turns more slowly. Inverting the diameters gives approximately 2967 rev/min, which is the most common error.

Why the other options are not the answer

  • A. 595 rev/min does not follow from 890 × 300/1000.
  • C. 2967 rev/min inverts the diameter ratio (890 × 1000/300); the larger driven sprocket must turn slower, not faster.
  • D. 445 rev/min simply halves the speed instead of applying the 300/1000 diameter ratio.

3. Which mechanical property describes a material's ability to return to its original dimensions once a deforming force is removed?

  • A. Malleability
  • B. Plasticity
  • C. Ductility
  • D. Elasticity
Show the answer and explanation

Answer: D. Elasticity is specifically defined as the ability of a material to return to its original shape after a deforming force is removed. Plasticity is the opposite: plastic materials do not return to their original shape. Ductility refers to permanent deformation under tensile load, and malleability refers to permanent deformation under compressive load.

Why the other options are not the answer

  • A. Malleability is the ability to deform permanently under compression (be hammered or rolled).
  • B. Plasticity is the opposite: a plastic material keeps its new shape after the force is removed.
  • C. Ductility is the ability to deform permanently under tension (be drawn out), not to spring back.

4. When a valve stem is leaking and the existing packing still has sufficient material, what is the correct first action?

  • A. Tighten the packing gland as firmly as possible to guarantee all leakage stops
  • B. Remove all packing from the stuffing box and install new packing rings
  • C. Shut the valve completely and leave it closed until the packing can be replaced during a planned outage
  • D. Slightly tighten the packing nut or gland, ensuring bolted glands are tightened evenly
Show the answer and explanation

Answer: D. The correct first action for a stem leak when sufficient packing remains is to slightly tighten the packing nut or gland; bolted glands must be tightened evenly to avoid binding the stem. Over-tightening causes extra friction and wear, so the gland should only be snugged enough to stop the leak. Replacing all packing is only necessary when insufficient packing remains. Leaving the valve shut without corrective action is not the recommended procedure.

Why the other options are not the answer

  • A. Over-tightening adds friction and wears the stem and packing; snug it only enough to stop the leak.
  • B. Repacking is only needed when too little packing remains; here there is enough.
  • C. Leaving the valve shut with no corrective action is not the recommended first step.

Question ID KE-A07-C02-Q006 · Unit A-7: Introductory Fluid Handling Technology · Report an error

5. Which device is specifically designed to protect sensitive computer and control systems from even a momentary interruption of AC power?

  • A. A load-shedding relay that isolates non-critical circuits during an outage
  • B. An automatic transfer switch (ATS) with open transfer capability
  • C. A key-interlocked tie circuit breaker connected to a standby bus
  • D. An uninterruptible power supply (UPS) with battery backup and inverter
Show the answer and explanation

Answer: D. An uninterruptible power supply (UPS) provides continuous power to sensitive systems, such as computers, controls, and communication equipment, that cannot tolerate even a momentary loss of power. It combines a rectifier, battery bank, and inverter to deliver seamless power during outages. An ATS with open transfer would still introduce a brief interruption, making it unsuitable for systems that require zero downtime.

Why the other options are not the answer

  • A. Load shedding drops non-critical loads; it does not keep critical loads powered through an outage.
  • B. An ATS with open transfer still breaks the supply briefly while it switches, which sensitive systems cannot tolerate.
  • C. A tie breaker switches the load between buses; it does not carry the load through the interruption itself.

6. Which of the following correctly pairs a combustible element found in boiler fuels with the compound it forms during complete combustion with oxygen?

  • A. Hydrogen reacts with oxygen to form water vapour (H2O)
  • B. Carbon reacts with oxygen to form carbon monoxide (CO)
  • C. Sulfur reacts with oxygen to form sulfur trioxide (SO3)
  • D. Nitrogen reacts with oxygen to form nitrogen dioxide (NO2)
Show the answer and explanation

Answer: A. The three combustible elements in boiler fuels are carbon, hydrogen, and sulfur. During complete combustion, hydrogen combines with oxygen to produce water vapour (H2O). Carbon forms carbon dioxide (CO2), not carbon monoxide, which is an incomplete combustion product. Sulfur forms sulfur dioxide (SO2), not sulfur trioxide. Nitrogen is not a combustible element and its presence in air is generally treated as non-reactive at normal combustion temperatures.

Why the other options are not the answer

  • B. Carbon monoxide is a product of incomplete combustion; complete combustion of carbon forms CO2.
  • C. Complete combustion of sulfur forms sulfur dioxide (SO2), not sulfur trioxide.
  • D. Nitrogen is not one of the combustible elements in boiler fuel (those are carbon, hydrogen and sulfur).

4A practice exam: FAQ

Does this make me eligible to write 4A in Alberta?
No. SteamTicket is exam-prep practice, not an ABSA-accepted education program. Alberta generally requires an accepted 4th class course (or another path ABSA lists) before you can sit 4A. See Alberta 4th Class exam eligibility and confirm with ABSA.
Are these real 4A exam questions?
No, and that’s deliberate. Real exam questions are secured and copyrighted; reproducing them would be unethical and illegal. Every question is original, written objective-by-objective to the public ABSA/SOPEEC 4th Class Part A syllabus (AB-054), written to the same public objectives as the exam, without copying any secured exam or textbook.
How is 4A different from 4B?
The 4th Class certificate has two papers. Part A (4A) covers the fundamentals: mechanics, thermodynamics, governance, safety, materials, fluids, electrical, controls, and an introduction to boilers. Part B (4B) is applied plant operation: pumps and compressors, boiler operation, water treatment, prime movers, refrigeration, and HVAC. You write them as separate papers.
What’s on the 4A exam?
One paper of 100 multiple-choice questions, 3 hours, 65% to pass, four choices per question. It covers the twelve Part A units of the SOPEEC 4th Class syllabus, from elementary mechanics and thermodynamics through plant safety, materials, fluid handling, electrotechnology, instrumentation, and an introduction to boiler designs and systems.
How many practice questions do I get?
596 original exam-style questions in the full 4A bank, each with a worked explanation, plus unlimited mock exams in the real 100-question format. You can also try 20 free, with no signup, before you buy.
Is it a subscription?
No. It’s $79 once for 4A, with lifetime access, including future updates to the bank. No monthly fees, and a 30-day, no-questions-asked refund if it isn’t right for you. Writing both papers? The 4th Class bundle covers 4A and 4B together for $99 once, also with lifetime access.
