Free working memory test for gridChallenge
Remember where the dots appear and in what order, while you answer questions about figures in between. The same setup as Aon's gridChallenge, with our own tasks.
How it works
- Dots appear one at a time in a grid. Remember where they were and in what order they came.
- After each dot you answer Yes or No about a figure: is it symmetrical, is the right one the left one rotated, or is the figure subtraction correct?
- At the end you click where the dots were, in the right order. If you click the wrong spot, you can undo the last click.
- Nine rounds in 9 minutes, with more dots at each step. Every judgment and every answer has its own time limit.

Positions and judgments
By difficulty
By round
Review of every round
First you see the correct order of the dots, with your clicks next to it; green means the right position in the right order. Below each round are your judgments with explanations.
Want more practice?
Do the exercise again; you get new dots and figures every time. You can also practice Aon’s other question types, or one question type at a time with an explanation right after each answer. Everything is free and you don’t need an account.
What gridChallenge looks like
gridChallenge is the Aon subtest for working memory. Aon gives it 9 minutes and nine tasks of varying difficulty, and describes the skill as keeping something in mind while you process other information. Our guide to Aon's tests covers the other subtests.
Aon's own screencast shows how it works. One dot at a time lights up among several gray circles. Short questions about figures come in between, answered with yes or no, and at the end you click the positions in the order the dots appeared. Practice sites describe the questions as alternating with the dots. The video also mentions three practice tasks before the test itself.
- Symmetry: is the figure the same on both sides of the center line?
- Rotation: is the right figure the same as the left one, only rotated?
- Figure subtraction: three small dot grids with lines, set up as figure minus figure equals figure. Is it correct?
How our practice test works
The tasks are our own. The dots appear in an even grid with 16 positions, so it works just as well with a finger, a mouse or a keyboard. The first round has two dots and the last one six, and figure subtraction only shows up in the last three rounds. You get one point for each position with the right number in the order and one point for each correct judgment, and you see both parts separately afterwards.
We haven't found an official description of how Aon scores gridChallenge, so the result here only tells you how the practice went. To practice Aon's other question types, take the free Aon practice test with tables, logic grids, switch codes and odd-one-out figures.

Frequently asked questions
What is gridChallenge?
gridChallenge is Aon's working memory test. According to Aon it takes 9 minutes and has nine tasks of varying difficulty, where you keep something in mind while you process other information.
Is this Aon's real test?
No. The tasks are our own and imitate the format: dots to remember, judgments in between and an answer where you click the positions in order. The score can't be compared with Aon's results.
Can you train your working memory before the test?
You can at least learn the format, so you don't spend time and focus on working out what is happening. Do both this practice test and Aon's own screencast before the real one.
