Our GAPAN tests are proving very successful. They also have a very high degree of correlation with both Morrisby and military pilot aptitude assessment, although there are different degrees of correlation in some areas of miltary assessment for the obvious reason that the miltary will also require a pilot to have the potential of flghting as well as flying.. .. .My advice would be to make sure that you can pass a Class 1 medical first, then take the GAPAN tests. Yes - I know that, to quote Mandy Rice-Davies, some of you will say "He would say that, wouldn't he" - but the GAPAN tests are a very worthwhile investment for anyone thinking of a commercial aviation career.
