Spatial awareness is an ability unlikely to be improved in a way that would affect aptitude testing results. Verbal reasoning can be, however, with training - but in which language?!
In UK, aptitude testing is used as part of the selection process for most sponsorship schemes and, as in Sweden, for the military. The tests are usually framed in such a way that an individual's underlying aptitude can be assessed whatever their experiences have been up to then. Psychological tests are also used, but are far less critical to the end result.
A below average result does not of itself mean that you could not become a pilot, or that you would not be offered a job by those doing the testing. Only a failure to reach the minimum standard would do that. If you are assessed as above average in other respects, you may well find that you can succeed.
