Some questions I vaguely remember from my OAR tests, I hope this helps!

Root 9 + Root 27

He held 400 newtons of force on his waist for minutes, how much work (joules) did he do?

The amount of power from an ac generator

Brick and feather in a vacuum which drops first?

log3 ((log8(log10(x)))) =-1

Work F x D x T x θ

Binary base , 7+8

Gravity mass on moon vs earth?

I had a nuclear reactor question with rods asking about cooling it down and heating it up brush up on that.

Find next number in sequence 1, 2, 5, 26?

7pie /4 radians is equivalent to?

If Mary rolls one die and chooses one card from a randomly shuffled deck of cards, what is the chance that Mary will roll a 2 or higher on the die, and will choose a heart form the deck of cards?

Find average x + 70 +75 +80, each test is 10% more than each other, what score needed to get average on class? (this is definitely on the test)

pretty sure this might be right.

test 1- score 70% weight 10% total points 700
test 2- score 75% weight 20% total points 1500
test 3- score 80% weight 30% total points 2400
test 4- score x% weight 40%

Anyone have suggestions for videos/resources that explain circuits beyond the basic theories like V=IR and series vs parallel? I watched the ones on Khan Academy but whenever I try to solve questions on the Barron's book or flashcards people posted here I end up struggling and confused

For circuits in series use this

V =	I	R
V sub (t) 'total'= V1+V2+V3+...	I sub (t) 'total' = I(1)=I(2)=I(3)	R sub (t) 'total' =R1+R2+...

For circuits in Parallel use this formula

V=	I	R
V sub (t) 'total'= V1=V2=V3....	I sub (t) 'total' = I(1)+I(2)+I(3)+...	R sub (t) 'total'= 1/R1+1/R2+...

#7 Voltage drop is equal cause the resistors have the same resistance
Look at the series table I sent you. V=I*R
We can solve this mathematically. Let's say the R1 and R2 are each 10 ohms and current, I, is 3 Amps.

Current, I, is I (t) = I1=I2=... So the current is 3 Amps across both resistors
Resistance ohms is R(t) = R1 +R2... so R(t)=10+10 ===>R(t)= 20
V (across R1)=IR ===>V= 3*10===>30 volts
V (across R2)=IR ===>V=3*10===>30 volts

Just took the test for a second time, first time was mainly to just get familiar and got 7/7/7 57. The scores were good but I have a VERY competitive class at my NROTC unit. Second time around got 8/9/8 60. Do not slack on the UAV flash cards, got 100% on the second try but the first time I missed a handful and let me say the feeling you get from the buzzer sound is reminiscent of this

. I used the Google drive posted over in study guide thread and it was a life saver. Study all the flash cards you can, study until you can't get them wrong not until you get them right. There was still questions in the aviation/nautical information portion I had never encountered but the intuition I built from genuinely understanding instead of memorizing really helped. Mechanical engineer with a 3.5 with pilot as my first choice, assignment in October/November so I'll keep you all updated. You all got this!

You do realize your not competing against your unit for slots as SNA or NFO, youre competing against every MIDN in the country

I took the OAR the past Wednesday, and got a 56, which is 6 points better than my first try in May. My recruiter declared it was an awesome score (his words), so my package will be submitted for the Intel 21Sept20 board on Monday. I never posted on this particular thread in the past few months, or at least I don't remember if I did.

A lot of these posts were a tremendous help! To be honest though, I'm very confident in my math skills, but for some reason the math was exponentially more difficult the 2nd time than it was the first. I guessed on a bunch of the questions, and ran out of time. That didn't give me much confidence going into my 2 weaker areas immediately. However, I pushed through knowing I studied many hours for this exam, and I'd do better than I did the first time. Good thing I was right! For anyone who is interested I'll break down what kind of questions I remember from the test later on, plus what I did to study. I will say one thing that helped me for the reading and mechanical comp was the 2020 - 2021 Newstone OAR Exam Test Prep Team book I got from Amazon via Ebay for about $30. There's 5 different tests in all 3 subjects in that book, and I recall the structure and difficulty of the Reading & Mech Comp practice tests were on par with the difficulty of the actual OAR. On the other hand, the practice math tests was at least 20 times easier in that book than on the exam. If I were to study again, I'd definitely spend more time studying logs, exponents, and factoring on Kahn Academy and other sources recommended on this thread.

If you had a 50 why did your OR have you take it again? The OAR once you have a score that qualifies you to go to board is not important once in the board. What is important once you get to board is your GPA and degree (depending on the designator).

Thank you so much for your input. That's very helpful. Based on your name here, I'm definitely going to trust your comments more than most on this forum. Reasons I retook the OAR is 2-fold. After the first time I took the OAR, my OR left it up to me whether or not to test again. He said he would do anything I said regarding my packet at that point, yet I thought he was also encouraging me to give it another go. Looking at the scores of his other recruits who got selected for Intel and those that were posting on here about being selected all had a minimum of 55 on the OAR (I don't think most of the candidates on her were going for Intel), so I thought it mattered to the board what my OAR score is. However, now after reading your post I guess I should've gone for it the first time. With your experience in this arena would you say that maybe my OR pushed me a little to retake because my college degree is religious studies/theology? Imo, up against engineers, math majors, and others I wouldn't fare as well with a lower OAR score, so I think maybe he believed a higher test grade would make my packet a little more competitive. What do you think?

In general OAR tends to follow GPA, so if a person has a high GPA they should have a high OAR, of course there are exceptions but looking at trends that is what you will see, now many of those selected for Intel or any other small designator that can be selective will often pick selectees that have a higher than average GPA, which leads to the higher than average OAR.

That makes perfect sense. I hope I make the cut! I'm going for the next upcoming board, so should find out the news by about mid-October. Fingers crossed!

Took my ASTB today and ended up with 57 7 8 7.

Math
Lots of DRT and work questions, some decent algebra questions. I think if you go through Kyles math practice tests you should be more than fine.

Reading
For some reason this was kind of hard to me, much different than what I was expecting. Nothing complicated but focused almost entirely on grabbing one sepcific detail out of a passage and was trickier than I was expecting.

Mech
Again nothing out of the ordinary here, lots of theory related to force and pulleys. If you read through the gouge in Kyles you will be fine.

ANIT
I got lucky here and the questions weren't that bad, lots of basic flight and boat questions. I didn't study as much as I felt I needed to, went through some flash cards etc.

PBM
I thought I did horrible on this. I play flight sims here and there and generally feel comfortable, but this was hard for me.

Overall I think as long as you cover the gouges out there and take some practice tests you'll do fine.

I saw a question a couple of pages earlier asking about a binary base of 7+8?

How would one go about solving this?

Thanks

I made a post about this question earlier on June 25th, 2020. I encountered this question towards the end of my OAR math portion. For me, this was the hardest math question on the test, but yeah after this question I started getting easier questions so yeah probably got it wrong. I re-looked at my notes and the actual question was something like:

Binary base 4 of 7+8?


I found that someone else had the same question. Show on the quote below:

Alright folks, I took the ASTB for the 3rd and final time today. 1st scores I got, which I submitted with my ECP package for an aviation guarantee was a 40, 4/5/5. I figured I'd be okay with those since the Marine Corps can give you a 1 point waiver. Word to the wise on that one, they won't give you an age waiver and a test point waiver. I did the Enlisted Commissioning Program, and since I was stationed in Pensacola, its made this process a lot easier for me with NAMI, and a test site here and I have to wait before going to TBS anyway, so why not try again. So I took it again in February and got a 40 3/3/3. Yup, I did worse. Round 3 was today, and I'm happy to report i got a 49 (I don't care that much about the OAR) 6/7/6. Like many I used this forum extensively for the last several months and it certainty helped a ton. APEX was even down this morning, but they got it fixed relatively quickly. I say this, for those who wish to take this exam, trust me and the hundred of others who have stated this forum works, and can make you successful, but that is completely up to you. I'm commissioned, with no real job right now, I have a son and wife whose a student and a nurse. I don't have a plethora of time to just study either.

Math section:
Its stupid important, and take your time! I think I ran out of time, APEX was acting slow and weird. However, I just cared about answering the question at hand to the best of my ability and trying not to guess, because right answers outweigh wrong answers. I put that theory to the test. Math equates to OAR and your AQR. I did get a binary question, and it was weird. Binary of 2 is 0010 or something which is 2x1 + 2x0. What is binary of 4 for (7 +8) or something like that. Answer choices were 15, 21,23,33. Yeah I guessed (when in doubt C it out).

Reading:
Yup boring, deduce what you can. Did see duplicate questions from previous exams.

MCT:
Mostly theoretical stuff, a bullet is dropped, and a bullet is fired from a gun horizontally, which one hits the ground first type questions.

ANIT:
Know them planes, and what aircraft did what, and general aviation stuff. I'm an Air Traffic Control Instructor, so most of that was fairly easy to me.

PBM:
Compass trick works, and I only got 1 wrong, and averaged roughly 2ish seconds. I took a little longer for a few of the non-standard direction ones.

Listening part:
By all means do the lean if you need to, being a controller I'm used to listening using both ears with information being fed to you. I also closed my eyes for this portion just like when I do an audio exam each year.

STICK and THROTTLE
Its not meant to be pleasant, and find your dead zones. They used the Saitek x52 set up, you can find it on Amazon for like a $139. They used to use the HOTAS Cougar. I bought the HOTAS for xbox 1 and played Ace Combat 7. I mean I think it helped some.

now the EMERGENCY section. This was truly helpful! FIRE: both dials down, hit clutch. The next one is Both dials up, hit clutch. and PROP, fuel dial to 50%, and power to 100%, hit clutch. Whoever had that up, THANK YOU. solved those in like a few seconds, and I was back to playing the chase game.

Seriously though I was the only one in mine, and I took breaks like it was cool. You can only move on from each section after hitting NEXT yourself. If you need a few minuted to decompress, by go do it. Figure out what works for you and don't burn through chances until you feel comfortable. Good luck future officers, and pilots. MARINES again, OAR mean nothing to us, just AQR,PFAR, and FOFAR. 4/6/6 to be exact, and you can can waive 1 point for any one of those, but not multiple.
