since there is no clear answer anywhere on what the test consists of, I am going to study according to what Alpha Aviation Academy has on their website regarding the assessment:
Alpha Cadet Selection for Cadet | Alpha Aviation Group
You can buy a practice version of the FAST/ADAPT Online on this website:
NZSkillsConnect
I found it to be very helpful. That is of course assuming that is the only test they administer to potential cadets on assessment day.
