Hey, I passed my briefing last November with a cat 2(6 months) for poor agility. At my first interview with a recruitment officer, he fired a number of speed/distance/time questions at me which I was simply unable to answer. I attained a B in Maths at GCSE, but at 24 and having studied politics had not been near the subject in years. I did some work before my briefing and attained 'above average' scores on my MAP tests, which hopefully reflects some improvement in my maths. No verbal test of s/d/t was made. I have my Main Board in late August and am aware that as well as an essential skill for my planning exercise, s/d/t questions are likely to be fired at me mid-interview by the Officers. My plan is to do s/d/t questions for some time each day on Speed Distance Time | OASC: RAF Officer and Aircrew Selection Centre - adding in one of my test planning exercises every few days from the beginning of August until MB. I am currently attaining 80-100% each time I run through the s/d/t questions, but with an average of around 30 seconds per question currently. Some are very quick, but a few stump me, taking considerably longer than average. Naturally I expect improvement. My question is, what level of s/d/t questions are fired verbally? For example: 1) What speed covers 16 miles in 48 mins? - No drama here. Common factor is 4, so 16/4 = 4 and 48/4 = 12. This gives me a ratio of 4:12, which is also 2:6 or 20:60 - therefore 20 minutes. 2) At 195 mph, how long does it take to travel 26 miles? - This is a pen and paper job for me, surely?! Are the verbal questions going to be like 1) and limited to friendly, easily divisible numbers? Am I right to suggest that questions like 2) would be above most people's non-paper ability? I'm trying to do these all in my head as much as possible, but there are always a couple that I have to get my pen and paper out for - hence I'm a little worried!
