Took my first OAR and got a 45 with no study time. Studying 3-4hrs a day for the past month and taking my next one in the beginning of December. My goal is definitely mid-50s. My background is a 3.0 gpa in Business and Finance, and going for supply. Plenty of material on this site has helped and I'll keep y'all updated for sure, good luck to everyone that's applying!
How’d you do??

If it is the Marines that you are gunning for, from what I have heard, they don't give a %*&# about the OAR. Only the x/x/x scores. I've been told that your target scores should be a 6/6/6...so w/ the scores u have I'd say ur in. Just double check and make sure w/ your Marine OSO if your scores are good. To give u a reference frame, my roommate got a 6/6/5 (I believe) and got a air contract recently. So, your looking great! However, he has a Marine PFT of about a 278. Your PT scores also look good so I'd say you are in!
Awesome man, that puts me at ease a bit. Thanks for the input.

Hey everyone,

Took the ASTB today and got 61 8/8/7
Since this thread made it possible, I thought I would share my experience.

Background: Electrical Engineering Degree gpa 3.5; Minors in Math and Physics; a few flight hours; passed private pilot ground school.

Math: Rate/Distance; algebra; exponents.
The problems I got all seemed straight-forward, nothing too complicated.
Tip: Good mental math is helpful. I had to get mine up to speed due to severe calculator abuse.

Reading:
Tip: Do as many practice tests that you can. Time yourself. Practice focusing intently on reading for long periods of time.

Mechanical: Pulleys (but more complicated than what I studied); 1 pitot static; work/energy conceptual problems; 1 electrical; 1 about splicing
There were a few questions that I had to guess.
Tip: This section requires a solid understanding of statics, dynamics, physics. I recommend lots of videos on the listed topics. If you don't have a technical degree, I recommend putting in some time on this.

Aviation/Nautical: WWII questions. When guessing, I clicked on the airframe that I recognized.
Tip. Watch a bunch of WWII/Korean/Vietnam/Gulf War documentaries over ships and aircraft. I recommend reading the entire Airman's handbook of Aeronautical Knowledge and understanding how each instrument works and the physics behind it (it will help with the mechanical part too).

UAV: Missed one; tried to go fast but still maintain accuracy. ~1.5s each.
Tip: Do the flashcards on these until you don't need to think about it.

NATFI: Just think which option you wouldn't do or would absolutely never do.

Dichotic: I think I missed a few? I practiced this though. Really hard to tell when one ear gets "A" and the other "8." I created an audio file that had a automated voice reading off letters and numbers.
Tip: Youtube - dichotic listening. Listen to two different podcasts or whatever in separate ears.

Tracking: I kept forgetting the stick was inverted despite playing inverted video games and that the throttle was not inverted... At first I avoided max deflection of stick/throttle, but then realized I couldn't keep up with the target.
Tip: Don't forget that the stick is inverted. Play games that involve multitasking. Try to adapt to the dead zone on the stick and throttle. Don't be afraid of maximum deflection. After a while the airplane moves almost as fast as the tracker, so if you want to stay on target, you have to keep up with it. If/when you are out of range, get back on the target QUICKLY.

Dichotic/Tracking: I practiced this by playing multitask games while listening to a string of letters and numbers. I am fairly sure it helped.
Tip: I believe the key here is to keep getting better at the tracking as the test continues. I started off a little shaky at first but once this section came I felt like I was doing better. Adapt quickly.

Emergency Procedure: I tried my best to track while fixing the emergency quickly
Tip: Just do the best you can. Read instructions

My advice:
Don't psych yourself out if you miss a problem or mess-up. Try to keep cool, and keep getting better as the test goes on. I know I missed a few.
The study guides and material on this thread are gold. Go back to when the test changed to the ASTB-E and start reading. If you can do all the problems here and in an in the other mentioned test prep books, I imagine you will do fine. If not, taking it again will help with the Performance Based sections.

The material on this thread will get you 60% there. Being a good test taker and building test taking skills will get you another 30%. But the last bit takes a lot of effort to know everything that could possibly be on the test. If it wasn't for ground school and some classes that I took, I would have missed several more. Spend as much time as you can afford on studying, every bit should help.

To everyone who posted before, thank you.

Taking the ASTB Jan 25th. Quick question regarding the UAV section (may have already been asked just couldn't find it in the forums): What direction is the drone or red dot going? Is the object going West or East? All the answers I've been getting from the flashcards would assume this object is heading East, but it is a little deceiving for me since the questions before this had a little red arrow showing which direction the aircraft is heading.

The tip of the yellow triangle is the direction the dot is heading. So in this picture, the dot is moving from left to right. Think of it like the tip of an arrow. The arrow points where the dot is moving.

Hello
I just came out of the ASTB test today. My scores were 55 7/8/7.

Background: Mechanical engineering major, 3rd year
30 hours ish of private pilot lessons.

My first two attempts I scored around 55 5/5/6 ish both times. I was only using the barren's book I purchased on amazon.
This third try I spent hours sifting through this discussion looking for all the resources I could find. After spending hours and hours of skimming, I studied and skimmed all of the material I had collected.
I have inserted links below to the majority of the material I have found. They are links to google drives which have been created by other users.

A few suggestions for those prepping to take it, I highly encourage you all to get a good night sleep before the test. This made the biggest difference in my ability to focus hard on the test during the time I was doing it. The first two attempts were while my semester was still going and had a ton of other things going on at the same time (especially since I am majoring in mechanical engineering) so I really didn't have much time to sit down and purely focus on the test when studying for it.
In addition to that, I highly suggest using the compass trick for the uav portion, trust me. And when you are allowed to practice the uav during the test, take advantage of that. I spent around 20 minutes going over the practice before entering the actual test in the apex software.
Finally, for me, it took me two tests to figure out by reading this discussion which number corresponds with the trigger and clutch button during the listening portion. When I did the test all 3 times, it skipped right past the instruction that showed which is which and straight into the test. If it wasn't for this discussion, I still wouldn't know which is which. For those who may encounter this issue, even numbers are trigger, odd are clutch. That is all I will say.

Cheers

Hello all! Have been following this forum since 2017, but today took the 1st steps. I am interested in crypto and intel, so I only to the OAR.

Background: I have degrees in Electrical (BS 3.3 GPA) and Computer (MS 3.68 GPA) Engineering. I am currently a Navy civilian but looking to do more. Am interested in cyber security. I am 24 but will be 25 next month. No prior service, would be first in my family.

Score: 57

As someone who HATES standardized exams (I spent 3 years building up the courage to take this exam), here's what I did:
Practice, I knew the material, but was not good at mental math (thanks higher education!) I went through the gouge on here from the very first page, just pulling links. Unfortunately, the old ones are broken but many others were nice enough to provided newer links. I studied an hour a day for 6 weeks (did not study the week of Christmas). The week before I did one practice test a day. I bought the Barron's book, the Master the Officer Candidates book, the Arco GRE book, and the Peterson's. I also purchased those little yellow GRE math and reading books.

The test was down a bunch too. We had to stop and close it at one point. Don't panic! It saves your progress! If anything, the lag let me mentally breath before the next question!

Math: One matrix problem (just know how to add 'em), D=RT (a bunch!), simplifying exponents like 16^(-3/4), basic volume geometry, the cost of business with two companies. Struggling to remember the rest. No logs, or geometry.

Reading: For me, the hardest section as I am not a reader. I definitely struggled here as the questions and answers got very easy, meaning it brought down my score. : ( I just had my fingers on the screen so I could compare words/phrases from the question to the answers to find any contradictions. People said it's all military but no, I got some science ones and one about mountains in there too. Do not hesitate to speak out loud. I was in a room alone so I read the passages aloud and even talked to myself during the other two sections.

Mechanical: I believe I did do well here, as I got the nuclear question (hint it talks about rods and reactors). My background is in EE, so the electrical questions were a breeze. As an EE, I can only suggest memorizing V=IR (and units -- I was asked this!) and understanding resistors, as from my experience they don't ask about capacitors or inductors. I memorized mechanical advantage and levers, but were not on the test. A lot to do with pendulums though and kinetic energy. Understand that a force in the x direction will not necessarily affect a force in the y direction (like a boat going perpendicular while being dragged downstream or a bullet being shot vs dropping a bullet) I was also literally asked to provide the equations for power and work as two separate questions.

Overall, was hoping to break 60 but the recruiter says I'm competitive. The board is in April so now just trying to get all the paperwork together. Lemme know what you think!

Thanks for the quick links! I have my exam Jan 25th. Do you use a Saitek Joystick? And when you say trigger and clutch what do you mean exactly?

A bit random but as I was studying for my second attempt at the ASTB-E, I just remembered that I saw a doppler effect question in the MCT secn. Please read this small article about the topic https://www.physlink.com/education/askexperts/ae26.cfm

The question was something like: The ambulance is approaching the observer, is the pitch increasing or decreasing? Obviously, it is increasing since it's approaching you it gets louder (think of when you were approached by a cop car, fire truck or ambi...it got louder). The science is as the truck approaches you the observer, the wavelength b/t the sound-wave and you decreases and, thus, the pitch increases (noise is louder)!

Again, super random but it's my 0.02 in case any of you get this question on the test (did not see anything in the guides about doppler effect and relied on knowledge from my physics class to answer it).

I got that question. I assumed based on experience that it was louder as it comes toward you.

Even though you both ended up with the right answer, the Doppler effect actually isn't referring to the volume of the noise, it's referring to the pitch. Pitch is not the same as volume. Here's a video on Doppler effect that does a good job explaining it:

Aaahhh...I see so the frequency of the sound-waves increases as it approaches the observer, thus, the reason for the louder noise and inc. in pitch. Also, the wavelength is smaller as the sound wave approaches you versus when it travels away from you. Thank you, that clears it up.

Hi first time poster,

I took the OAR today and got a 49. Feeling pretty discouraged/disappointed in the score because I knew I would need 50 to do intelligence and am now basically kicking myself. I’m thinking I’ll just study more and take the test again. I studied a lot of the google drive provided here. Trying to decide if I should just go SWO and not restest again. Or maybe do a waiver for the score. Any advice would be appreciated. Thanks!

Also B.S. is in Cyber Security, GPA 3.7
Navy reserve 7 years- rate AME
