Took the ASTB today and got a 58 6/6/6/ on form 5. The administrator of the test was not too enthusiastic about my scores and after reading through this thread I will most likely be retaking as it seems that 6s don't seem to be competitive for NFO. But enough about me, on to what I remember about the test. I studied out of the Barron's book until I could do every mechanical and math problem in both practice tests. And this

I read through portions of the FAA handbook to clarify principles of Atrickplay's study guide that I was unsure about. I also used the ARCO book, but probably the least out of all the materials.
Math- This was easier than expected though I found myself stretched for time in the end. I got too caught up on some word problems and that cost me a lot of time. I wouldn't worry about the algebra portion of the math section because it was incredibly easy. It was the word problems that got me. There was one similar to the pizza problem on Atrickplay's Study Guide but it was with different numbers so make sure you understand the concept and not just how to solve one specific problem. I also specifically remember a question about average test scores e.g. Tom scored 71, 76, 73, 70, what 2 scores will he need to average an 80 on all 6.
Reading - Seemed that the hardest part about this section was forgetting that your prior knowledge about the subjects that the passages are addressing is irrelevant to the answer. Just focus on what the paragraph says.
Mechanical - Like the math, easier than expected. Hardly had to do any equations, but the test asked for some specific mechanical information about types of instruments which weren't in any of the materials I used to study.
Spatial - I felt like I did really well on this section; like I only missed 2 or 3. However, my score says otherwise. It is true that the angles are more difficult than in any of the practice books but I did not find this to be the most difficult section of the test.
Aviation/Nautical Knowledge - I studied a decent amount for this section, but obviously not nearly enough. I recall a question about Amelia Earhart, Chuck Yeager, the Messerschmitt ME-262, and Vx (which I spaced on and got wrong) but there were still a large portion of knowledge that was not included in Atrickplay's Study Guide or Barron's. It has been said before, but if you really want to do well on this you have to study the FAA Handbook. There is such a large pool of information to draw upon for this section.
Supplemental - All aviation/nautical information with some question repeats. I was stumped on one question about clouds that was in this section . The question asked: What type of cloud is white, fluffy, and found at high altitudes. The answers were: nimbostratus, cumulus, cirrus, and altostratus. I guessed nimbostratus but none of those answers really seemed to fit. Also, and this has been said before, know the minimum load factor for the FAA. This question has been brought up before and I still have no idea what the answer is. The answers for the load factor on the test were: 2.4, 2.8, 3.4, 3.8. If anyone knows the answer to the load factor question please let me know because I can't seem to find it through google or the FAA handbook. There were also a lot of questions that stumped me in the section that were not in Atrickplay's or Barron's.
What I learned from this experience was that if you want to do well, to go for those 9s on the Aviation/Nautical and Supplemental portions, you have to study the FAA handbook. I memorized probably 80% of Atrickplay's aviation/nautical info and it still got me a 6 (though you could probably get a 7 if you studied it well enough.) I want to thank everyone who contributed to this thread and all the gouge they have provided. Good luck when you take the test!
