Had an interesting experience today taking the ASTB, but ended up with a good result so I'm pretty happy.
OAR: 67
AQR: 8
PFAR: 8
FOFAR: 8
Anyway, went in, and throughout the math, reading, writing, FAR, and aviation/nautical sections the program was very slow. Whenever I submitted a response to a question it would take 3-15 seconds to move to the next question. But no time went off the timer, so it was no significant issue. However, when I got to the PBM section, I got to a screen with a little radar and the words "downloading PBM instructions, this may take a few minutes", and it would not move past the screen. We tried rebooting the program several times, and still got nowhere. Since there was someone else waiting behind me to take the OAR behind me, my processor told me to go get myself a lunch, so the next guy could take his OAR, and that she would try to fix the problem. So I went and ate lunch, came back and filled out the BIRV, and waited for a while for the dude to finish the OAR. My process0r had made some sort of change, so I went back in and tried again, and it finally booted up after another long wait. Was a weird experience, would like to hear if anyone else has had that happen to them.
As for each section, the best I can remember is this:
Math: Lots of algebra, a matrix multiplication, some logarithms, fractional exponents, etc. Some problems I found it easier to plug in the various answers rather than solving. This was the only section in which I ran out of time.
Reading: I kept wishing for this one to be over, most of the time it would seem like all 5 of the answers could be correct
Mechanical: I feel like I could have studied differently for this one, lots of ideal gas law, no classes of levers or gear problems.
Psychological Problems: Like everyone in this thread has said, a bunch of choices between terrible options. "I have severe problems with authority" or "I doubt myself constantly"
Aviation/Nautical info: Decks of a ship, all of the aerodynamics surfaces of a plane and how they work
PBM: Use the compass trick, and be sure to write down the emergency procedures. Apart from that, this section was actually really fun, I enjoyed myself.
I used Barrons "Military Flight Aptitude Tests" and "Mechanical Aptitude and Spatial Relations Tests", as well as the GRE GMAT review, as well as some of the study guides and spatial orientation flash cards to study.
