Hey all,
Long time lurker, first time poster.
I wanted to start out by saying THANK YOU to everyone who has posted here and on Reddit, as well as those who have created practice apps and websites. Your contribution is essential to people like me who had no idea what they were getting themselves into.
This morning I took my first run at the ASTB and was lucky enough to score 65 9/8/8.
As people have said before, the content here closely matches the testing content, but I will debrief my experience below.
MATH
I was only allowed one sheet of paper front and back, which was a hinderance as I tend to write big and messy and have practiced with the ability to change out paper as needed. The questions asked here were not by any means high level math, but they WERE difficult, and I ended up guessing on probably half of them. Know your square roots, especially those with numbers ahead of the root sign. Know how to find area of a shape given something like "if the base is 7 times the height, and the perimeter is 80x". know how to find a percentage of a percentage, especially in situations where discounts are added together on the price of a car. Know how to find the perimeter of a triangle if you're given the hypotenuse as 3(sqrt of 2). Know how to find probability of someone both rolling a die AND pulling a certain type of card from a deck. As mentioned before, don't worry about knowing formulas for area, they are all given, and they only asked maybe one or two. Know how to find the area of a circular track given the interior area and the width of the track itself. I was not asked any matrices, logarithms, or advanced geometry. I DID, however, rush to complete this section and anything I couldn't figure out in a minute or so I just guessed and moved on.
READING
Not much to say here, just read fast and choose the correct answer. The topics discussed were SO much less interesting than anything that any prep book has. The passages are so incredibly dry and technical. Try reading Aerodynamics for Naval Aviators by Hurt, that's about the level of jargon and writing.
MECHANICAL.
Almost no calculations, it really is just your ability to reason. Know what happens when you put larger or smaller tires on a car and what it will do to your speedometer. Know what happens when metals heat or cool down. Know how to mathematically balance a lever with a load on one end. I would say just focus on the WHY of mechanical principles.
AVIATION/NAUTICAL KNOWLEGE
Mostly just aviation knowledge, quite a bit of helicopter related questions, and a few questions on general quarters, deck crew colors, and certain aviation weapons systems. Know the parts of an aircraft, to include parts of military-only aircraft. Know various types of aircraft as well. Very few if any ship parts/nomenclature, and no questions on rates or ranks. For the pilots out there, this will be a lot of "Duh" stuff. For example- "which part of the wing moves? how does one counteract adverse yaw?"
EVERYTHING ELSE
Everything else on the test has, in my opinion, been beat to death. The gouges on the psychomotor part are really accurate, and it's a difficult part of the test for sure. Be aware that there IS a terrain identification portion, and its hard (0, 30, 60, 90 degree marks) and you have to select the heading based off of a compass with all the available options; there isn't 4 options like the app has. In essence you have 12 options to choose from for every question.
Thats all I got. Again, I really do appreciate all that everyone here has done. This is an awesome group of people that really do want to see everyone do well. Study hard, and study often, and you will do just fine.
