A textbook tells you what to study. This tells you where you actually stand. Pick your paper below, sit 25, 50 or 100 real exam-format questions, and get a chapter-by-chapter debrief. Free, no credit card.
Every 2nd, 3rd and 4th Class paper is here. You get one free exam, so pick the paper you are least sure about: that is the one worth measuring.
All six papers, 2A1 through 2B3. Applied mechanics, thermodynamics, boilers, prime movers, plant systems, and electrotechnology.
All four papers, 3A1 through 3B2. Mathematics and applied science, legislation and administration, boilers, and prime movers.
Paper 4A, the whole exam: mechanics, thermodynamics, plant and fire safety, electrotechnology, instrumentation and boiler design.
Paper 4B, the whole exam: prime movers, pumps and compressors, boiler operation, water treatment, refrigeration and HVAC.
Pick the paper you want to sit.
Not a quiz, and not a teaser. It is the same question bank and the same debrief a paying member gets, on one paper.
25 questions in 45 minutes, 50 in 90, or the full 100 in 3 hours. The 100-question run is the real thing: same count, same clock, same multiple-choice format as the paper you will write.
Every question is drawn from the live bank members study on, weighted toward the difficulty that actually decides a pass. Nothing on this page is written specially to look easy.
Your result is not a percentage. It is a breakdown of which chapters you are solid on and which ones you are not, so you know where the next month of study should go.
2nd and 3rd Class get AI feedback explaining why the answer you picked was wrong, not just which one was right. 4th Class gets a full statistical breakdown by chapter.
This is question 3A1-4, exactly as it appears in the exam. Have a go before you scroll.
A pump and skid assembly has a total mass of 2000 kg. The coefficient of static friction between the skid and the concrete floor is 0.26. What minimum horizontal force is required to start the assembly moving?
Correct: 5101 N. F = μs × m × g = 0.26 × 2000 × 9.81 = 5101 N.
The three wrong answers are the three mistakes people actually make on this question, which is the point of the debrief:
Get this wrong across several questions and the debrief will not just say "applied mechanics, 60%". It will show you that friction problems are where you are losing marks, and whether you are losing them on the physics or the arithmetic.
You choose: 25, 50, or 100 questions, drawn from the real exam-format question bank for the paper you pick. Every length ends with a full chapter-by-chapter debrief showing exactly where you're strong and where you're not: with AI feedback for 2nd and 3rd Class; 4th Class gets a full stats breakdown.
No. The free practice exam is completely free: no credit card, no trial that converts automatically, no commitment. You just verify your email so we can send your results and prevent abuse.
No, the free practice exam is one paper only, once, verified by email. Choose whichever paper you're least confident on: 2nd Class, 3rd Class, or 4th Class Part A or B. Want more? A subscription unlocks every paper for 2nd/3rd Class, or exam-specific access for 4th Class Part A/B.
That is your choice when you start. 25 questions gives you 45 minutes, 50 gives you 90 minutes, and the full 100 gives you 3 hours. The 100-question run matches the real paper on both count and clock, so it is the one to pick if what you want to know is whether you would finish in time.
Yes. Every jurisdiction's paper is now 100 multiple-choice questions in 3 hours with a 65% pass mark, and the free practice exam uses that same format and the same question bank our members study on. The questions are weighted toward the difficulty that actually decides a pass rather than the easy end of the bank.
Yes. It runs in the browser on a phone, tablet or desktop, with nothing to install. Most people sit the 25-question version on a phone and save the full 100-question run for a laptop and a quiet three hours.
A textbook question tells you the right answer. This tells you why the answer you picked was wrong, and then aggregates that across the whole paper into a chapter-by-chapter breakdown, so you finish knowing which two or three chapters are costing you the pass. That is the part a book cannot do.
Sit it anyway, and sit it early. A diagnostic taken before you study is more useful than one taken after, because it tells you where to spend the months rather than confirming what you already suspected. Nobody sees the score but you.
A free practice exam shows you where you stand on one paper. A subscription gets you full course access for your certificate: every paper with AI tutoring for 2nd/3rd Class, or exam-specific adaptive practice for 4th Class, all the way to exam day.
