What the test is like

BNP Paribas switchChallenge

Built by Aon

Format
Aon's deductive reasoning test, also called scales sx. Two rows of symbols, what went in and what came out, and a four digit operator that rearranged one into the other. You name the operator, not the output, and the later items chain two operators and hide one.
Timing
Time boxed rather than a fixed question count, and adaptive: your score is what you get right inside the window, so two people can see a different number of items. Most accounts say six minutes, some say five.
What is uncertain
Accounts vary on the clock and on whether wrong answers are deducted. Aon does not publish BNP Paribas's configuration, so our version picks one and says so on the page.
How to practise
Switch is built on this format.
