1,200 original questions across mechanical reasoning, numeracy, literacy and abstract reasoning — every single one with a worked explanation, because knowing you got it wrong teaches you nothing on its own.

Practice & Prepare
Drill each skill area, then sit a timed mock exam.
WHAT IT IS
Drill one skill area at a time, or sit a full 40-question mock exam against a 30-minute clock, drawn fresh every time. Then read the reasoning behind every answer you got — right or wrong.
Section practice
Pick a skill area and a question count.
Pick a section, a length and a mode. Study mode explains as you go; test mode holds it back until the end.
A fire crew uses 100 litres of water in 10 minutes at a constant flow rate. At the same rate, how many litres will they use in 30 minutes?
Find the flow rate, then scale it up. Rate = 100 L ÷ 10 min = 10 L/min. Over 30 min: 10 × 30 = 300 L.
Not an answer key — the actual reasoning, written out, on all 1,200 questions. That is the whole point of the app.
Scores broken down by skill area, with your strongest and your focus area called out, and a trend line across every session.
DRAWN, NOT SCRAPED
Pulleys, gears, levers, hydraulics, circuits and pattern grids — all drawn specifically for these questions, at a size you can actually read on a phone. No recycled question bank sits behind this app.
THE FOUR SKILL AREAS
The four areas a firefighter aptitude assessment tests, each with an equal, deliberately built bank behind it.
Gears, levers, pulleys, hydraulics, forces and how things move — the area most people find hardest, and the one with the most diagrams behind it.
300 QUESTIONSRatios, rates, percentages, unit conversion and the practical calculations the job actually asks for — flow rates, pressures, ladder lengths, crew timings.
300 QUESTIONSComprehension, inference and clear written communication — built on realistic documents: standard operating procedures, incident reports, safety bulletins, station notices.
300 QUESTIONSPattern sequences, 3×3 matrices and odd-one-out problems that test reasoning independently of anything you already know.
300 QUESTIONSWHO IT'S FOR
Career or volunteer, first attempt or fourth. If there's a written aptitude stage between you and the job, this is built for it.
You've never sat a psychometric assessment and don't know what the questions even look like. Start in study mode and let the explanations teach you the patterns.
You know the format already and need volume plus honest feedback on where you're losing marks. Sit mock exams and read the per-section breakdown.
School was a while ago and ratios, percentages and mechanical advantage need dusting off. 600 numeracy and mechanical questions, all worked through.
HOW IT BEHAVES
No account to make, no notifications to turn off, no version of this app that works better if you pay again.
Every question and diagram ships inside the app. It runs on a train, in a basement, or anywhere with no signal.
No analytics, no crash reporting, no advertising SDKs. Your practice history is saved on your device and never leaves it.
Open it and start. There is no email address to hand over and no login standing between you and the questions.
No subscriptions, no in-app purchases, no ads and nothing to upsell you once you're inside. One price, everything included.
Launching on iPhone and Android. No practice app can tell you what will be on your assessment — what it can do is make the formats familiar, so on the day your attention goes on the problem rather than working out what's being asked.
