Prepare for the AON - Assessment exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: In the matrix Row 1=(2,4,8) and Row 2=(3,9,27), following the same rule, what is the missing third value in Row 3 starting with 4 and 16?
Answer: B. 64
Explanation:
The correct answer is 64. Each row uses consecutive powers of its first value: the first row is 2 raised to the first, second and third powers, and the second row follows the same pattern with its own first value. Row 3 starts with 4 and 16, so the third value is 4 to the third power, which is 64.
48 is wrong because it comes from multiplying 16 by 3, which is not the row rule. 32 is wrong because it doubles 16, which ignores the pattern. 56 is wrong because it only adds to 16 and fits no rule in the earlier rows.
Rule to remember: test one rule against every complete row before applying it to the incomplete one. Check both multiplication and powers.
Question: You are given an urgent task but realize you lack the knowledge to complete it. What should you do?
Answer: B. Admit the gap to your manager and ask for guidance or resources.
Explanation:
The correct answer is to admit the gap to your manager and ask for guidance or resources. This deals with the problem early and keeps the work on track.
Guessing to appear competent is wrong because a confident but incorrect result can cause more harm than a short delay. Delegating to a junior colleague without preparation is wrong because it passes your problem to someone who has not been set up to handle it. Waiting until someone notices is wrong because it hides the issue and wastes time on an urgent task.
Rule to remember: in situational judgment questions, the strongest answer is usually honest, timely and constructive. It involves the right people and does not shift responsibility or conceal a problem.
Question: Two gears are connected. Gear A has 40 teeth and Gear B has 20 teeth. If Gear A rotates at 30 RPM, how fast does Gear B rotate?
Answer: C. 60 RPM
Explanation:
The correct answer is 60 RPM. Meshed gears have speeds inversely proportional to their tooth counts. Gear A has 40 teeth and Gear B has 20, so B is the smaller gear and turns faster. Multiply 30 by 40/20 to get 60 RPM.
15 RPM is wrong because it reverses the ratio, as if the smaller gear turned slower. 30 RPM is wrong because it assumes the gears share a speed, which is only true when the tooth counts match. 120 RPM is wrong because it doubles the correct result, for example by applying the ratio twice.
Rule to remember: the smaller gear spins faster, and the speed ratio equals the inverse of the tooth ratio.
Start with Aon's official preparation page and your invitation. Note which tests you have been asked to take, the deadline, and which tests are timed. Then build your practice around those.
For the personality questionnaire, there are no right answers to rehearse. Answer consistently and honestly. Because you may repeat a module at interview, work in a way you can reproduce. Spread your sessions across several days and do the real tests when you are rested and undisturbed.
Whether you are applying for a job, re-entering the workforce or just want to make sure you are up to par with your peers, an AON assessment test is a great way to go. It helps you determine your strengths and weaknesses, and it is also a good way for employers to see whether you're a good fit for the company.
There are several types of AON tests, including numerical reasoning and spatial orientation tests. These tests measure a variety of skills, including numerical skills, spatial skills and deductive reasoning.
Aon's Spatial Orientation Test has the following features: It tests your ability to understand spatial relationships and your ability to determine the location of objects. It also measures your ability to use mathematical concepts and work with data.
Aon's Numerical Ability Test is quite challenging, and requires you to quickly tally up numbers to determine the right answer. It also tests your ability to recognize and use numeric data and graphs.
While Aon's Aon Assessment test is one of the more complicated tests, it is a great way to determine whether you have what it takes to succeed in your next job.
