About Aon scales cls

Aon lists scales cls as its Inductive-logical Thinking test: 12 tasks in 12 minutes. Each task shows six 3×3 grids of letters and digits. Three carry an orange bar (set A) and three a blue bar (set B). You work out what each set has in common and assign four unmarked grids to orange or blue. See Aon’s candidate page.

Wrong answers count against your score. A task counts as right only when all four grids are in the right set, so take the minute each task allows.

Rule types in our tasks

  • A character sits in a fixed cell
  • A character appears an exact number of times
  • A character appears anywhere in the grid
  • A digit or a letter sits in a fixed cell
  • A row contains a character
  • A column contains a character

Every task is original, generated fresh for each sitting and checked by a validator for a single correct answer.

Questions about scales cls practice

What is Aon scales cls?

scales cls is Aon’s Inductive-logical Thinking test. Each task shows six grids of letters and digits in two marked sets and four unmarked grids. You assign each unmarked grid to the set whose rule it follows. Aon gives 12 tasks in 12 minutes.

How is scales cls scored?

Wrong answers count against your score: our results show a net score of correct tasks minus wrong tasks. A task counts as right only when all four grids are in the right set, and the review shows which grids were right.

What kind of rules come up?

Rules are about characters and where they sit: a 7 in the center, the letter K exactly twice, a digit in the top-left cell, a row that contains a given character. No grid follows both sets’ rules.

How should I pace it?

Twelve minutes for twelve tasks is one minute each, the slowest pace of the Aon ability tests. Check one candidate rule against all three grids of a set before testing it on the unmarked grids.

Can I return to an earlier task?

Not in our timed test: all four grids need a set before you move on, and a finished task stays closed. Within a task you can change an assignment as often as you like.

What is free, and which pass covers this practice?

The example on this page is free with no account and does not use an attempt. Each practice card shows your account’s access before you start. One Aon Practice Test pass covers the scales ix, clx and cls timed tests, their learning drills and the full practice test. Saved reviews stay free.
