so mister supercool, why do you think they test you before the training starts instead of training you(because it's "possible"
)?
and why do you think they pay thousands of euros for psychologists to analyse your skills?
and why do you think all ansp's test their applicants?
of coouuurse because it can be learnt.
of course you can improvie your skills. but as an example:
you are not trained and can run 100 meters within 12 seconds,someone who has trained for some years can run 100 meters within 11.5 seconds.
what do you think. who is better? you without training or he with a lot training?
of course you!
and why is training useless? because they want to compare applicants without any experience. it is impossible to compare applicants with experience and applicants without expericenes together.
