Took the ASTB for the 2nd time today and scored a 65 7/7/7. Here's some of the concepts I encountered and some advice:
Math
- Quadratic equations (ax^2 + bx + c = 0)
- Simple probability (If you roll a fair dice and pull a card from a deck, what are the odds of rolling a 6 or higher and pulling a card with a heart suit)
- Functions (Solve for x in f(x) = 3(1/4)^x if f(x) = 2
- Radicals (Simplify sqrt(3) + sqrt(27))
- Arc length (If a slice of pizza has an area of 6pi in^2 and the angle on the end of the slice is 60 degrees, what is the arc length of the outer side of the slice)
As well as some other stuff I can't remember, but Kyle's guide will pretty much get you there
Reading
- Pretty much just reading a paragraph and choosing an answer that best describes the contents of the paragraph. I believe the Barron book has a section on this, might suggest looking up reading comprehension problems from the SAT.
Mechanical Comprehension
- Bernoulli's principle
- Circuits (is the current flowing out of a point greater/lesser than the current flowing in)
- Work (Defining work, does pushing a block up a steeper ramp require more/less work than a less steep ramp)
- G-force (defining, if a plane is flying in a loop where does the pilot experience the most Gs)
- Pulleys (comparing pulleys to see which requires the most force to lift a weight)
- Flow rate
ANIT
- Good mix of aviation and nautical information, aviation questions were oriented towards flight components i.e. what controls movement about the longitudinal axis, what instrument is used to measure banking, with no questions on airports. With a degree in aerospace engineering this required zero studying but YMMV. Nautical was oriented around ship components like what is a keel, etc.
NATFI
- This just sucks. 99 questions where you pick from two unflattering options, mine had the added bonus of taking 10 seconds to load the next question every single time. Nothing to study here.
PMB
- UAV section was first and the compass trick made a world of difference, felt like I was on fire in this section. The format for me was exactly like the UAV cards where you have a map with an arrow pointing towards the target. Managed to get all of them correct in less than 2.5 seconds, disappointed my score didn't reflect how I felt.
- Jantzen sim helps for the HOTAS section, if you have a high refresh rate monitor I would recommend dropping your refresh rate to 59hz because going from 1440p 144hz to a crappy old monitor really threw me off. I would also recommend getting the Logitech X52 HOTAS that
@elariosa95 mentioned or something similar, that was the exact setup my NRD used for testing. I borrowed my friend's badass Thrustmaster HOTAS Warthog set to practice for this portion and going from hefty metal sticks to light plastic threw me for a loop. As far as my scores go, I felt like I tracked fairly well and got all of the emergency protocols correct, but missed a couple of the dichotic listening prompts.
A little disappointed I didn't score any 8s or higher but I think it's a solid improvement. Hoping that I don't have to take it ever again, I had my test scheduled for 1000 and didn't wasn't able to start until 1130 due to technical difficulties which I feel impacted my performance.
