DAA Mechanical Comprehension Practice Test

The Defence Aptitude Assessment (DAA) is an essential part of the joining process, with the tests that form it being recognised as strong indicators for in-role performance at all ranks, and across all Branches and Services of the Royal Navy.

In order to give you the best chance of passing the full DAA, these example questions are your opportunity to practise:

- You should always try and achieve the highest mark in each section
- Getting more familiar and comfortable with the format and process will also help you perform to your best
- We recommend you practise at least a couple of times, but more if possible
- But also make sure you take time out between your practises - allowing your fingers, eyes and mind to get some rest
