Sorry to be dull, but is it still only two attempts allowed at RAF Officer/ Aircrew aptitude tests - your best score being carried forward if you manage to pass?
For those interested, I sat the tests (aircrew) a couple of years back, so here's a glimpse of what it was like (if it's still relevant):
You are woke up at silly o'clock on test day (kinda expected continental breakfast..hehe) - this is usually on the second day of attendance to OASC, whereas the first day is settling in and meeting the other candidates (think that was the only part i passed).
You do your usual morning stuff (whatever that is) and then you have some breaky (kinda ok if your stomach can handle food at such an early time but my stomach usually receives its first load at 8.30' ish). After Breakfast, you have a briefing on what you are about to face: the aptitude tests (big gulp!). The tests last around 6 hours, from what i can remember, and (naturally) they ain't easy (IMO) - strange environment and constant countdown clock in the corner of your computer screen all add to the pressure. The first wave of tests are OK and have been mentioned before on here: hand and eye co-ordination, memory, verbal reasoning, etc, etc, etc. All seemed to be going well until i hit the orientation type part (travel ne 50 miles, sw 20 miles, etc), the maths bit (speed, distance, time) and the statistics section (seriously hated that): time is the biggest enemy in the tests, but i believe, that most of the tests are designed not to be completed in the time allocated.
My advice to anyone sitting the tests, is not to think about tests you feel you have not done so well on whilst at the computer: just forget them and concentrate on the next lot of nasties coming up (think the staff say something like this any way). Also, being nervous and tense will most probably just hinder your performance, so try to relax and enjoy. Remember they want to pass you. Unfortunately, for me, i didn't have the score required for my first choice branch, and was therefore, ask to see the on-site RAF career guy about my other branch choices - sadly, he had gone home early with a cold (awwwww, bless).
Anyway, to cut a long story short before i bore everyone to tears, i, and around half of the group, didn't make it to stage 2 of OASC - we weren't the right cogs to fit the machine, known as RAF, and had to leave. What seems to always stick in my mind is that if you are told to leave OASC the scene is reminiscent of a house-mate, or more, being evicted from the Big Brother house (well, sorta) - just there are no crowds of screaming fans and family to meet you when you leave the OASC doors. Btw, I'm not a fan of Big Brother.
Another tip that (i think) i read from a bit of booty literature: failing to prepare is preparing to fail.
