I just took the astb on Friday. What has not been mentioned is that there is a set of equations that is provided by the test (computer version) for you. I didnt need them (or I didnt think I did) so I can not promise what is listed but I do remember the area for a circle and the volume of a sphere. Of course the whole test matters, but if you are trying to go aviation, focus on the spacial appreciation, the aviation and nautical info, and the mechanical comp. These are what make up the majority of the pilot and flight officer ratings. The Barrons's military flight aptitude test prep book has what I believe to be the best spacial app. coverage. But be careful the computer images are not great. Good luck. Just remember "take your time, but hurry up"
Just point of reference: 8, 7, 8, 68
