The Royal Navy Psychometric Test is 4 part multiple choice, 30 questions in each section & you should aim to get a minimum of 50% correct in each of the 4 sections to be assured of a good pass & to leave viable job options in the Navy, should you not make the physical grade as a Royal Marine. If you score less than ten out of 30 in the English or maths sections, it's an automatic fail for any job. The questions aren't hard, but you need to work fast. There is now a full recruit test app on this link: https://www.royalnavy.mod.uk/practice-naval-service-recruitment-test-marines/ If you fail it can be as much as 12 months for a re-sit, so beware falling at the first hurdle. The booklet is available free,from your AFCO and there are practice tests on the Royal Navy Website. The test sections are as follows: Reasoning 9 mins, Literacy 9 mins, Numeracy 16 mins, Mechanical Comprehension 10 mins. Thirty questions in each section. In total 120 questions in 44 minutes. The introduction of a minimum score in the mechanical comprehension section for Other Ranks is catching a lot of guys out - don't underestimate it, the pass Mark in is now 12/30. For Officers, minimum scores have been introduced in the Reasoning, Literacy & Numeracy. For Officer you need to aim for 75% correct in each section. You get a free practice test booklet from the AFCO which is an excellent guide to what to expect. The questions are drawn directly from all three versions of the Recruiting Test with only the numerical values changed. The Practice booklet is only valid if you follow the instructions to the letter & practice against the clock. Those who fail the recruiting test frequently bemoan that the example booklet was "nothing like the real test" - it's exactly like the real test if you follow the instructions. Online tests are of limited value as it's a paper & pencil test, however a lot of people say the Brain Training games on a DS helped them. Free Online Psychometric Tests can be found if you are prepared to look. You should go through the test as fast as you can to simulate the real thing. A good example of online tests can be found at: Civil Service online test which offers a simulated Naval entry test. To my mind it's probably the most representative of the online tests available, albeit online rather than paper & pencil. Having had a crack of the book pictured below, I can fully recommend it - some bits are harder than the actual test but if you practice to this level, you should be OK and leave plenty of fallback options available: Another good book to maybe borrow from a library (again harder than the test, but good for practice- IF you feel you need it) is IQ & Psychometric Testing by Phillip Carter another one, believe it or not is the Verbal, Non-Verbal & mathematics sections of 11+ Examples. It sounds mad but the questions are virtually identical- again it's the timescales that make it difficult. You only have 9 minutes to complete 30 questions in the verbal section, same again in the non-verbal & 16 minutes for the 30 maths questions. Sounds easy- try it! The generic: Practice-Tests-Armed-Forces(ISBN: 9780340926550)is reasonable in my opinion, but possibly a little easier than the real thing. The Ultimate Psychometric Test Bookis another reasonable example to borrow from your nearest library. Not particularly a fan myself, but others recommend the How 2 Become series.
