4B power engineering practice exam
Part B is the applied half of the 4th Class — the day-to-day plant: lubrication and bearings, pumps and compressors, boiler operation, water treatment, prime movers, refrigeration, and HVAC. Practise with 778 original exam-style questions written objective-by-objective to the public SOPEEC/ABSA 4th Class syllabus, sit unlimited mock exams in the real 100-question format, and walk in knowing exactly where you stand.
Original questions, written objective-by-objective to the public ABSA/SOPEEC 4th Class syllabus (AB-054) — not copied from any textbook or secured exam. One-time purchase, lifetime access. Independent; not affiliated with SOPEEC, ABSA, Technical Safety BC, TSSA, or PanGlobal.
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: 778 questions keyed to every AB-054 Part B objective, unlimited 100-question mocks in the real 3-hour format, and a worked explanation on every answer.
$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.

4B or 4A — which do you need?
The 4th Class certificate is two separate papers. Most candidates write Part A first, then Part B — but you can prepare for them in any order your regulator allows.
Part B (4B) — this page
Applied plant operation: lubrication, pumps and compressors, boiler operation, water treatment, prime movers, refrigeration, and HVAC. 778 questions.
Part A (4A)
Fundamentals: mechanics, thermodynamics, governance, safety, materials, fluids, electrical, controls, and an introduction to boilers. 584 questions.
Writing both? The 4th Class bundle covers Part A and Part B together.
