Hey y'all! Just retook the ASTB today and scored
50 6/7/7, an improvement from my first attempt (
42 4/5/5)!
All in all, studied for ~3 months, 4-6 hours a day (though had many days where I couldn't do that, so maybe 2hrs at the most for bad days). I also brought snacks this time.
For the math and mechanical comprehension sections, make sure you're familiar with all rules, formulas, and laws. In the MST, they do provide a list of formulas, but it's much more efficient to have an arsenal of formulas ready in your noggin. Besides the study guides mentioned below, Khan Academy and
this GRE book helped tremendously.
The Barron's book had most everything I needed to know for the ANIT. Trivium helped a bit too. A few other resources found on this forum (listed below) and from random Google searches helped out as well. I can't say that you'll know
everything from studying these guides, so just obtain as much random information as you can.
PBM: I'll try not to repeat what has already been said, so my advice is to prioritize quality and accuracy, take a deep breath, and go. There is a practice section for the UAV portion that you can take as many times as you want. Ace that a few times before proceeding to the actual UAV portion.
I wrote down all instructions and displayed them in front of me for the relevant portions. For example, for the dichotic listening, let's say that clutch is for odd numbers and the trigger for even numbers, I wrote "ODD" on the left side and "EVEN" on the right side of a folded piece of paper. This (writing the directions) is most important for the Emergency Procedures.
Below are the posts that I found most helpful, but it doesn't hurt to look around this forum for more. Just make sure you give yourself enough time to fully soak in all the information.
These YouTube videos helped with familiarizing myself with Aviation and Nautical Information:
Do the practice problems and tests and make sure you know how to do the problems you get wrong (I know that's kind of obvious, but it's easy to be lazy).
Study smart, study hard, take deep breaths, bring water, bring snacks (and/or mints), aim high, and slay it.
