Ten questions, and the explanation after every one.
These are ten of the 629 questions in the Firefighter Aptitude Lab, across every reasoning area. Answer one and you get the same explanation a buyer gets: the working, what was wrong with the option you picked, and the rule to take away. You answer as a guest, and the sample clears when you leave.
An attack line flows 180 L per minute. How many litres flow in 2 minutes 30 seconds?
That is the sample.
The lab has 629 questions, each explained the same way. It starts with a 56 question diagnostic, builds a daily plan from what it costs you, and brings each mistake back on a later day as a fresh question on the same skill.
