Try an Original Audio Listening Sample
FSO’s aptitude outline includes understanding oral information. Use this original recording for listening practice: listen once, recall the details, then replay to review. This sample’s player allows replay. Follow your own administrator’s playback and note-taking instructions on test day. The separate quiz below focuses on math, mechanical, map/spatial and judgment skills.

Three Free Firefighter Aptitude Questions with Worked Answers
These additional original examples are separate from the scored 15-question quiz above. Try each question before reading its answer. They demonstrate selected skills, not an official exam format.
1. Math: water remaining
A practice tank contains 800 litres of water. An exercise uses 15% of it. How many litres remain?
Answer: 680 litres. Ten percent is 80 litres and five percent is 40 litres. The exercise uses 120 litres in total, so 800 − 120 = 680 litres remain. A common mistake is reporting the amount used instead of the amount left.
2. Mechanical reasoning: meshing gears
Two external gears mesh directly. Gear A has 20 teeth and turns clockwise at 60 revolutions per minute. Gear B has 40 teeth. What are Gear B’s speed and direction?
Answer: 30 revolutions per minute, counterclockwise. A gear with twice as many teeth turns at half the speed: 60 × 20 ÷ 40 = 30. Directly meshing external gears turn in opposite directions. Work out speed and direction separately.
3. Map reasoning: relative position
Starting at a station on a square street grid, you travel four blocks east, three blocks north and one block west. Where are you relative to the station?
Answer: three blocks east and three blocks north. The east and west movements partly cancel: 4 − 1 = 3 blocks east. The northward movement remains three blocks. This asks for your final position, not the eight blocks travelled.
