There is no fee — food, accommodation and travel are provided. The Royal Navy publishes no single pass mark.

Sample Royal Navy AIB Tests Practice Questions

Try these sample questions to test your Royal Navy AIB Tests exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A patrol boat travels 84 nautical miles in 3.5 hours. What is its average speed in knots?
A.21 knots
B.24 knots
C.28 knots
D.294 knots
Explanation: Speed equals distance divided by time: 84 ÷ 3.5 = 24. A knot is one nautical mile per hour, so the boat averages 24 knots.
2What is 15% of 240?
A.24
B.36
C.40
D.16
Explanation: 15% of 240 is 0.15 × 240 = 36. A quick mental method is 10% (24) plus 5% (12), which sums to 36.
3A ship's crew of 180 is divided into watches in the ratio 4 : 3 : 2. How many sailors are in the largest watch?
A.40
B.60
C.80
D.90
Explanation: The ratio parts total 4 + 3 + 2 = 9, so each part equals 180 ÷ 9 = 20. The largest watch is 4 parts: 4 × 20 = 80.
4Complete the number sequence: 3, 7, 15, 31, 63, ?
A.95
B.121
C.127
D.94
Explanation: Each term is double the previous term plus 1: 3×2+1=7, 7×2+1=15, and so on. Therefore 63×2+1 = 127.
5A fuel tank holds 4,500 litres. After a transit it is 40% full. How many litres remain?
A.1,800 litres
B.2,700 litres
C.1,500 litres
D.900 litres
Explanation: 40% of 4,500 is 0.40 × 4,500 = 1,800 litres. The remaining 60% (2,700 litres) has been used.
6Without a calculator, what is 248 + 376 + 152?
A.776
B.766
C.786
D.676
Explanation: Group friendly numbers: 248 + 152 = 400, then 400 + 376 = 776. The AIB numerical test allows no calculator, so quick grouping speeds mental arithmetic.
7A data table shows a frigate covered 312 km, 288 km, and 360 km over three days. What was the mean daily distance?
A.320 km
B.330 km
C.312 km
D.300 km
Explanation: The mean is the total divided by the count: (312 + 288 + 360) ÷ 3 = 960 ÷ 3 = 320 km.
8If 6 sailors can paint a hull in 12 hours, how long would 8 sailors take, assuming equal work rates?
A.9 hours
B.16 hours
C.10 hours
D.8 hours
Explanation: This is inverse proportion: total work is 6 × 12 = 72 sailor-hours. With 8 sailors, time = 72 ÷ 8 = 9 hours.
9A bearing of 045° is taken. A ship then turns 90° clockwise. What is the new bearing?
A.315°
B.135°
C.090°
D.225°
Explanation: Turning clockwise adds to the bearing: 045° + 90° = 135°. Clockwise rotation increases the compass reading.
10Convert 3/8 to a percentage.
A.37.5%
B.38%
C.0.375%
D.3.8%
Explanation: Divide 3 by 8 to get 0.375, then multiply by 100 to get 37.5%. Knowing common fraction-to-percentage conversions speeds the timed numerical test.

About the Royal Navy AIB Tests Exam

The Royal Navy Admiralty Interview Board (AIB) is the final selection stage for officer candidates, held at HMS Sultan in Gosport, Hampshire. Its written psychometric component is a battery of timed multiple-choice reasoning tests covering verbal reasoning (about 20 minutes), numerical reasoning (about 25 minutes, with no calculator) and abstract or non-verbal reasoning (about 13 minutes), alongside speed-and-accuracy and spatial-orientation papers. Before reaching the AIB, candidates sit initial aptitude testing now delivered as the tri-service Defence Aptitude Assessment (DAA). The AIB also includes a recorded interview, an essay, a planning exercise and group/leaderless tasks, which assess teamwork and leadership but fall outside this multiple-choice practice set. Attendance is free, with food, accommodation and reasonable travel provided.

Royal Navy AIB Tests Study Tips from Top Performers

1Practise no-calculator numerical work daily — percentages, ratios, averages and rates — so mental arithmetic is fast and accurate under the 25-minute limit.
2Build vocabulary for verbal reasoning: drill synonyms, antonyms and analogies, and read short passages to answer using only the information given.
3Train abstract reasoning by spotting consistent rules — rotation, reflection, counting, alternation and odd-one-out — rather than guessing on appearance.
4Time every practice section and avoid spending too long on any single item; there is no penalty for guessing, so attempt every question.
5Learn core service knowledge: Royal Navy ranks, the carrier and submarine fleet, main naval bases, and the AIB structure at HMS Sultan.
6Prepare concise, structured answers for the recorded interview and essay, and practise the planning exercise to show teamwork and leadership.
7Confirm your officer-branch requirements, the Defence Aptitude Assessment, and AIB attendance logistics well before your board date.

Frequently Asked Questions

What is the Royal Navy AIB psychometric test?

The AIB psychometric stage is the multiple-choice written part of Royal Navy officer selection. It is a timed battery of reasoning tests — verbal (about 20 minutes), numerical (about 25 minutes, no calculator) and abstract or non-verbal (about 13 minutes) — alongside speed-and-accuracy and spatial papers.

Where is the Admiralty Interview Board held?

The AIB is conducted at HMS Sultan in Gosport, Hampshire. Officer candidates attend in person for the board, while initial aptitude testing and some interview elements may be completed online.

How much does the AIB cost?

There is no fee to attend the AIB. During your stay, food and accommodation are supplied free of charge, and reasonable travel costs are reimbursed in line with Royal Navy policy.

What score do I need to pass?

The Royal Navy does not publish a single fixed pass mark for the psychometric tests. Prep guidance indicates officer candidates are expected to score in the upper range, often around three-quarters per reasoning section, which is higher than the standard for general entry roles.

Can I use a calculator on the numerical test?

No. The numerical reasoning test is sat without a calculator and under a strict time limit, so fast and accurate mental arithmetic is essential. Practising mental methods for percentages, ratios and averages is strongly recommended.

What other stages are in the AIB besides the tests?

Beyond the psychometric tests, the AIB includes a recorded interview, an essay, a planning exercise and group or leaderless tasks. These assess communication, teamwork and leadership and are not multiple-choice, so they fall outside this practice set.

What aptitude test do I sit before the AIB?

Initial aptitude testing is now delivered as the tri-service Defence Aptitude Assessment (DAA), which replaced the Naval Service Recruiting Test. It is a battery of timed psychometric papers covering verbal, numerical and abstract reasoning.

Can I retake the assessment if I am unsuccessful?

Candidates who are not successful may be eligible to reapply and reattend after a set interval, in line with Royal Navy recruitment policy. Confirm the current re-attendance rules with your careers adviser.
