I recommend doing the problems you are sure you can do first, then go back and work on the others ones, and then when you have about a minute left, just go to the blanks ones and fill in bubbles at random. that usually works well on any test. I used the ARCO study guide also and it helped tremendously. When i took it, i think it was called the MFAT, Military Flight Aptitude Test. It had the same stuff on it though, just a different name. It helps a ton on the Spacial apperation section. The best way for that section is to use logic, and process of elimination and it will be obvious which is the right one.
As for the biographical section, even thought it might sound like it is the wrong answer, it is probably the right one and the one they want to hear. I think they actually like it when you answer "yes" to questions that are like, "have you ever gone on a high speed joyride just for the thrill of it?" i think they want to know you take chances and are adventurous. That is just my 2 pesos though.
