RAF OASC Selection Tests
The RAF Officer and Aircrew Selection Centre (OASC) consists of a series of interviews, tasks, and aptitude tests. Various mental arithmetic tests are included that are designed to determine your suitability for your chosen role. Chief amongst these are the speed, distance, time tests which are designed to check if you have the mental capacity for keeping tabs on numerous, fast-moving, airborne objects. This website offers you timed tests, similar to those you will find at OASC, to help you prepare.
Speed Distance Time Test
- The test is 10 questions of varying difficulty.
- Some may appear too hard to do in your head, but don't worry.
- Have paper and pencil ready to help you at first - but NO calculator.
- Soon you will begin to notice patterns in the numbers and shortcuts you can take.
- Here's a hint - all the numbers, including the answer, are whole numbers.
There are certain pitfalls that you will come across when doing these calculations:
- Make sure to remember the units you are working with - minutes, or hours? Miles per minute, or miles per hour?
- Try and guess-timate a 'ballpark' answer first, to check against the answer you calculate.
