Thanks for the offer, seanofthedead86. I'm scheduled to take the ASTB around mid-August and have a few concerns. I have some background with flying, so those related sections are not too foreign, but I have heard the image type/quality changes from the practice books to the actual exam. And maybe before I go into much more depth, what did you do for preparation in terms of study guides or other resources, and what served as the best?
Use the study materials from the site I linked in my last post. Stuff is golden. As far as books are concerned, I used Barrons "Officer Candidate School Tests." Its golden as well. I bought Cliff Test Preps "Officer Candidate Tests" but I would stay away from that one. Way too much useless information. I also used two books from Peterson's (can be found here:
http://www.nelnetsolutions.com/dod/), the "Military Flight Aptitude Test prep" and the "Officer Candidate Test prep". Do the practice questions and practice test.
The Marine Gouge, Airpatrick's study material, the Barrons book, and the Petterson's books were all more than enough, I thought, to study for the test. My suggestion as far what to focus on; Math and Mechinical are the most important (not that everything else isnt) but it is kinda hard to study for the Reading Comprehension. IMO, your either gonna get it or your not. Do some practice questions to get the feel of how they are set up but don't dwell on it. For Math and Mechanical, do the practice tests, and do them again and again and again until you get all the questions right and do them within the allotted time. If you do this, you will be able to finish the actual test with time to spare.
A strategy that worked for me on the real test, in terms of finishing with enough time, was that if I knew I wasn't going to be able to finish a question in a timely manner, I flagged it and skipped it, and went on to the next. No use wasting a bunch of time on one question when their are many more that you can answer correctly quickly. Doing this, i had enough time to go back to the questions I skipped and at the very least guess the answer, which s better than nothing.
