Good Afternoon, I've just returned from the AFCO having passed my aptitude test. I thought it best to write a few tips from my experience to benefit others. 1) The test was harder than the booklet distributed by the AFCO. I highly recommend purchasing some aptitude test practice papers from WH Smith etc. 2) Dress well, most of the other candidates came in wearing jeans and looking generally scruffy. 3) Arrive about 15mins before the allocated time, read the Navy News or other literature whilst waiting. 4) Definately practice against the clock. I managed to complete all my questions within the set time, but only just. 5) Relax, ask all the necessary questions before the test. They will go through it but don't be afraid to ask. 6) Read the question properly. One chap mentioned to me after the test that he thought he got 5 questions wrong for misinterpretting the question. Hope this helps those at a similar stage to myself. I'll try to write something similar once i've sat my interview.
