ASTB - Prep/Study Guide feedback


Well-Known Member

Thanks for the timely response. I appreciate that because my wife was worried that it would take some time. I think the biggest thing that will hold me up is getting my medical files and physical.
It can take N3M a week to review the documents once a physical has been completed, so best to plan on the next board.

Took the OAR today and figured I'd share everything I used to prepare in case it helps anyone else.

Score: 59
Studied: ~2 months -- first month a couple hours on the weekend + lots of time searching for relevant info and 2nd month at least an hour every day after work + more on the weekends. As a caveat I have been out of school for 7 years and my job has nothing to do with math or physics, so I had to re-learn basically all of the material for the math and mechanical sections.

If I were to do it over...
- I would start with a practice test to figure out the areas I needed to most help and then buy the relevant books. I overstudied some areas at first because I thought I needed to know way more physics than the practice tests included.

Overview of What to Study:
- https://www.med.navy.mil/sites/nmotc/nami/Pages/ASTBOverview.aspx
-- This was the best guideline of what to study that I found on the internet. And I'm pretty sure I searched the entire internet. Wish I had found this sooner.

Practice Tests:
- http://www.petersonspublishing.com/OfficerCandidate/
-- They will send you an access code via email. You only get one code and you can only take each section once. Once it's scored, you're done, so plan accordingly.
- http://www.nelnetsolutions.com/pdf/free/masterofficercandidate.pdf
-- There is a full practice test at the end of the book. You have to time yourself. They do a good job explaining the answers but some of the diagrams / answers were not correct.
- https://www.med.navy.mil/sites/nmotc/nami/Documents/ASTB_SampleQuestions_13May14.pdf
-- Not a full practice test but gives a good idea of how to gauge how hard the hard questions will be. Doesn't explain wrong answers but you can use the internet for that.
- https://www.triviumtestprep.com/astb-practice-test/
-- Not the best content wise, but I was worried about my timing so this helped with that.

Study Materials:
Khan Academy - search for a subject and watch lectures if you need stuff explained to you in order to 'get it'
- Princeton Review GRE Math Prep https://www.amazon.com/gp/product/0451487869/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
--Good explanations / step by step solutions and felt like this covered basically everything I needed to brush up on.
- https://www.proprofs.com/flashcards/topic/astb
-- There's a ton of content on here. Search by subject. A lot of it looks like it was directly from the Arco book
- http://www.petersonspublishing.com/OfficerCandidate/
-- This is a second link to the same Arco book from before. There's a mountain of practice Qs in here.
- I also made my own flash cards and carried them around with me pretty much everywhere and got a mental math app and did that during my commute (no calculators...)
- https://www.airwarriors.com/community/index.php?threads/astb-prep-study-guide-feedback.28142/page-2#post-484550
-- Patrick's study guide was REALLY helpful

Good luck :)

I would like to thank everyone for the resources here, they were of great help to me. I had the mixed blessings of being off of work on disability pay for a broken bone so I had plenty of time to study, and then even some extra time as my test got pushed back for computer systems being down. I was hoping to get the test done before I got back to my construction job as it's pretty fatiguing.

Anyway, with the help of the resources here I managed to pull off a score of 75 of the OAR. I did not take the other sections as I am too old for any aviation work. I will second Patrick's study guide as being very useful. Amarie's post directly above mine was also very useful as it condensed a lot of things in one place for me. I also found GMAT study books to be useful for math practice.

Again, thank you to all of you for your help and resources, and good luck to all future test takers! Study hard!


I hope this is okay but just looking to help out. I was selected SNA and heading to OCS in a few weeks. I have a bunch of ASTB study material to give away - books, note-cards, print outs, etc if anyone is interested in them? I bought them all on amazon. Not looking for any money except to just cover the shipping cost. Shoot me a PM if interested. Good Luck!

Good Afternoon,
This is my first post to the forum so please go easy if I am posting out of the required forum area. I just completed the OAR for the second time. My first test was a month ago and I earned a score of 40. I did minimal preparation thinking I had the math down pat. I was pretty disappointed with myself but realized my math scores were seriously lacking. I felt the reading and mechanical portions were not where I needed to focus. I hired a tutor from Wyzant and we focused only questions from Peterson's study material and examples that were similar in nature. I retook the test again today and scored a 50. Not what I wanted but it was what I needed for IWC. So now I have to wait for the board which will convene in May from what I understand.
Tips for those who may need it:

Math - Algebra, probabilities, averages, fractions and exponents.

Algebra - normal problems using PEDMA
Probabilities - 4 white marbles, 6 red marbles, 9 green marbles and 12 yellow marbles - What is the chance you'll get 1 green marble
2 normal dice - what are the chances you'll roll a 12
Averages - You received an 88, 71, 68, 91 and 85 on 5 out of 7 tests. What do you need to score on the last 2 in order to get an average of 88
Fractions - 1/8 of your crop is given to charity. If your crop is 3 1/2 tons, how many tons were given to charity
Exponents - 2 n-8 = 665 (n-8 is the exponent)

Reading - Just read and pick out the sentence that best describes the meaning of what you're reading. This is when I developed a serious headache. ha

Mechanics - Pulleys, density with objects in water, gravity formulas, inclined planes, physics theories, circuits including resistor, amps and current

I used material from this site as well as the math tutor and Peterson's OAR study guides that I downloaded from Air Warriors. I couldn't have gotten the score I needed without this site. I appreciate everyone who shared information that I was able to use.

Here is the base info for my package. Thoughts?

Age - 41
Profession - Systems Engineer on a government contract
GPA - 3.84 Information Technology Management
OAR - 50
12 years prior enlisted
LORs - O5, O5, O4, Civ. with PHD in Computer Science (Coworker)
Professional Certifications - MCSA, MCSE, Sec+, AWS (I chose to let my CCNA expire to focus on servers)
8+ Years of management experience

Thanks all.
