What it is

Symbolic and abstract reasoning items give you shapes, letters, numbers or symbols that follow a hidden rule. Your job is to find the rule and use it. Nothing needs to be memorized. Every answer comes from careful comparing and checking.

There are two families. Figure items show simple drawings: a series to continue, a 3 × 3 grid with one empty box, a set with one odd figure, or a pair of figures whose change you copy. Symbol items use letters and numbers: a secret letter code, a made-up operation sign, a number machine, or a repeating line of symbols.

Why it matters on the exam

These items appear in the Analytical part of the Professional exam. They look strange at first, so many examinees guess. With a fixed method, each one becomes a short, sure task.

The same habit helps at work. You spot what changed between two versions of a form, follow a coding scheme for files, or apply a stated procedure in the right order.

Rule 1 of 6The one-change rule for figure series and analogies
Compare each figure with the next and name the one thing that changes: turn, count, shading, size or position. Check that the same change happens at every step, then apply it once more.
Worked example 1 of 4A shading cycle in a series
Which figure comes next? The pentagons are shaded: none, half, full, none, half, ?
  1. Figure A
  2. Figure B
  3. Figure C
  4. Figure D
  5. Figure E
Step 1 · Ask the five questionsThe shape, size, turn and position stay the same. Only the shading changes.
