with respect to SITW that is completely untrue, I took computer based aptitude tests for a certain organisation and failed the lot. I simply made a decision that I would not let these b/s tests stunt my career. I spent the next 3 months finding books and visiting websites, and brushing up mental arithmatic etc. I went to take the tests again, and not only did I pass but I totally cleaned up.
Also when I was 16 I totally messed up the RAF tests, to the extent that they told me not to bother again, then 2 years later I passed them (but decided not to work for the government)
The SHL website is pretty good, also many books in the major shops, I used to be a poor student, so I'd buy a few, photocopy the relevent bits, take em back and then do the same a couple more times, also libraries are good and if you have access to one a university graduate service office usually have loads of stuff.
OK it's true that you either have apptitude or not TO AN EXTENT but that does not mean you can't train yourself to pass the tests, and with the same hard work and dedication become a successful pilot. Just depends how much you want it.
Those who say otherwise are usually exceptionally talented, and a certain amount of arrogance has led them to believe that the rest of the world are unable to improve themselved to a level which they are lucky enough to have naturally. all it takes is a decision. peace.

Remember the only natural pilots were those who hatched out of an egg.
