AOSB Aptitude

It tests potential to train as an officer rather than existing military knowledge. Reasoning tests measure how you handle unfamiliar verbal, numerical and abstract information under time pressure; planning exercises test structured thought; group tasks and the interview assess leadership, communication and motivation.

The reasoning sections are pitched at a good graduate-standard level but are designed to be demanding under time pressure. Most candidates find the numerical and abstract sections hardest. Difficulty is relative: the board is comparing you with other applicants, not applying a fixed pass mark you can target.

Retake and reapplication rules depend on the stage reached and the board's decision, and they change. Do not assume a fixed waiting period. The official recruiting site sets out the current policy, so confirm your position with your candidate support officer before planning a second attempt.

The aptitude and practical assessments run across a full board programme rather than a single short sitting, with reasoning tests, planning exercises, group tasks and an interview spread over the schedule. The official body publishes the current timetable for your intake; check its site rather than relying on second-hand accounts.

Start with verbal and numerical reasoning, because they improve fastest with timed practice and error review. Add abstract and spatial practice in short frequent sessions. Then rehearse written planning under a strict time limit. Leave group-exercise and interview preparation until your reasoning is consistent.

Work in strict timed blocks, then review every wrong answer to identify whether the error was method, misreading or pace. Keep an error log and revisit it weekly. Accuracy first, then speed. Untimed practice feels productive but trains the wrong habit for a timed test.

Running out of time because of perfectionism on one question; guessing without eliminating options; weak mental arithmetic slowing numerical work; unstructured planning that ignores constraints; and, at interview, vague answers about why you want a commission. Fixing pace and structure gains more marks than extra content.

Yes, in a focused way. Be able to discuss a few significant international and defence-related stories, explain why they matter and give a reasoned view. Breadth of headlines is less useful than depth on a small number of topics, plus a clear sense of how they connect to the Army's role.

Physical performance forms part of the overall assessment, so arrive already conditioned rather than starting training at the board. The official site publishes current fitness standards and the tests used. Treat fitness as a separate preparation track running alongside your reasoning practice.
