Start with Aon’s own preparation
Aon’s candidate preparation page explains the process and provides practice resources. Read your invitation for the deadline, equipment requirements and assigned modules. Follow the instructions on each test, including how answers and any errors are scored.
Match practice to the task
- Numerical reasoning: practise extracting values and units from tables or charts when that is the assigned format.
- Arithmetic: review calculations, ratios and percentages when those are required.
- Verbal reasoning: distinguish what a passage states from what you assume.
- Logical reasoning: explain the rule behind an answer before moving to new examples.
- Questionnaires and judgement tasks: follow the actual instructions; arithmetic drills do not prepare these formats.
This is our general preparation checklist. It does not mean every Aon assessment contains all of these tasks.
Scoring and practice results
Do not assume every module reports the same scale or that the reference group consists of prepared applicants. The employer uses the assessment results within its own process. Brain Preflight’s levels are separate from Aon’s scoring and cannot predict your recruitment outcome.
Plan around your deadline
Try the assigned familiarisation material first, then identify a specific problem to review. A short session reviewing mistakes is more informative than repeatedly chasing a score without understanding the instructions. Use the session history to see which exercises you want to revisit.
In the app, open Calculation grid and Logic sequences for numerical and logical items, and Same or not for checking tasks. The app has no verbal reasoning or table-based numerical exercise; its English word games are vocabulary tasks, not passage-based reasoning.

Questions before you start
Is this the same assessment pilots take?
Not necessarily. Aon offers different assessments and employers select different combinations. Your invitation and assigned practice materials are the relevant reference.
Do Brain Preflight scores count toward an Aon result?
No. They are internal practice indicators in an independent app, not scores on the employer’s assessment.
