I was given the impression during my aptitude de-brief that the battery of tests returns data on a series of skill areas. To pass in a certain branch, you require a certain minimum score in a number of select skill areas. Whether each test returns results on only one skill area, I don't know. I would be inclined to say no, as there was only one or two result indications for memory ability but many tasks that involved remembering things.
Funnily, I scored 3 in numerical recall and one other, but got two 8s, and the rest were 9 and 9* (stanines). I knew I was bad at memory tasks, so imagine my suprise when the Boarding Officer said he thought I had a photographic memory. Doh!
Not that it mattered, cause I'm perspex equipped in the vision department. Bring on the Blunty trade list baby...
Incidentally, I seem to recall people passing Pilot but not Nav or Fighter Controller, and vice-versa.
