There are considerable benefits in taking the GAPAN tests, because the accuracy of the scoring by their experienced testers is held in high esteem by the professional flying training industry. Feedback to GAPAN has shown that those who score well in the tests
will acquit themselves well during their flying training. Furthermore, I understand that HSBC also recognise that a loan applicant with a good GAPAN test result represents a sound financial investment risk.
So, if you really want an honest and well-found assessment as to see whether you've got the 'right stuff' for a career in civil aviation, you would do well to consider taking the GAPAN tests. You can find further details at
