does anyone know how to solve this?

log-base x (sq-rt 2) = 1/6

getting lost on how to do this one.

getting lost on how to do this one.

Here you go buddy, view the image below for a step by step solution. To clear any confusion here are the rules I used to solve this problem (I also wrote the rules down on the image attached below). Ask up if you've got anymore questions...

1. log-base a (b) = ln(b)/ln(a)
2. (x)*log(a) = log(a^x) .....(this rule also applies to the ln function!)
3. log-base b (f(x)) = log-base b (g(x)) => f(x)=g(x)

49/6/7/7 (OAR/AQR/PFAR/FOFAR) Second Attempt
43 (OAR) First Attempt

I re-tested the OAR yesterday, and took the aviation portion today. I am extremely happy with my scores, and like most people on this site, I would like to share my experiences to help others. I will include at the bottom a google drive that has been passed around that I found extremely helpful. There are other sources and books that I used to study, but I felt that what helped me was looking for as much material as I could. A huge resource for me was Khan Academy. I am a visual learner, and Khan Academy covers anything you could imagine being on the OAR. Finally, by pacing myself and dedicating 1-2 hours a day towards studying (for about 3 months), I felt that I gave myself the opportunity to cover as much ground as possible.

Math Skills Test:

I dedicated the most time towards this section and felt that it paid off. I got mostly arithmetic, word problems, and probability. I did not come across any logarithms or matrices.

Stay calm. Personally, whenever I tried to figure out whether a question was harder than the last one, I would take a breath and try to take each question as they came up.

Reading Skills Test:

I spent very little time studying, and I wish that I had studied more. Like most other things, if you quiz yourself every now and then, you should be fine. Take your time.

Mechanical Comprehension:

Most of the questions that I got were conceptual and a few with numbers. If you search on Cram or Quizlet, there are tons of flashcards that were helpful.

Aviation and Nautical Information:

Again, Cram and Quizlet are great resources. A few questions on evolved aircraft - "What aircraft was refit to refuel aircraft during Operation Iraqi Freedom." I also had one that said, "If a plane was 80lbs overweight, how much fuel would I need to dump in order to correct the issue?" (Gas 6lbs/gal) The nautical questions were more common knowledge than the aircraft.

Spacial Apperception/Performance Based Measures:

For the UAV, I put too much pressure on the time that I answered 3-4 wrong.

For PBM, just take the punches with a smile. During each phase, I would focus on each task as well as I could. Then between each section I would then laugh to myself and do some breathing to relax. As everyone says, write the emergency procedures down. I even folded my paper so it was standing up when I would look down at it.

Extra Advice:
I basically did all the things @dallaslayman suggested in his post. Personally, I over analyze everything. So, trying to take each section, then each question at a time really helped me. Always feel free to ask questions. I owe so much to this forum and this website. Good luck to anyone testing!

My favorite part of this post is the tri-fold emergency procedures, I did the same haha. Well done Sir & congrats. ??

ALSO, if the idea of taking the entire test in one day seems daunting, talk to your recruiter about breaking it into two sections. My recruiter suggested that I break it up when we initially talked about it, and I would recommend taking that route if you have the time/patience.

What kind of word problems and probability problems did you see? Did you see any geometry on any of your attempts?

Holy shit you can do that? I think that would make it easier to be honest.

Geometry, I think maybe one or two, but nothing rediculous. I had a question where there was a triangle on a line and I had to find the outside angle based on two angles inside the triangle.

Probability was two of "If Ben rolls 2 die, what are the chances he gets 8 on the first roll?" and one that was something like "If the probability of getting a blue shirt with a black tie is .15 and the probability of getting a blue shirt is .25, what is the probability of getting a black tie?"

As for the rest of the word problems, they were all things that I have seen, or variations of what I've seen, on these practice tests. Hope that helps.

Apparently, everyone that I have talked to has done it in one day. When I went to the OR office, and he told me that I could split it, I was shocked. But I immediately jumped on the opportunity when I heard another OR say that you could do it that way, they just have to be within 30 days of each other.

Went in this morning at 0700 ready to knock out my first attempt only to be informed that the APEX system was down. Pretty disappointing but I can't argue with an extra weekend of study time. I wonder if anyone else had this issue today. I'm in Jacksonville FL

How do you solve "If the probability of getting a blue shirt with a black tie is .15 and the probability of getting a blue shirt is .25, what is the probability of getting a black tie?"

I'm getting frustrated with the more "challenging" probability problems.

I am not sure if I got it right, so please someone call me out if I am wrong. But I assessed that the probability of getting both is lower than getting each individually. So, I broke it down by seeing that the x*.25=.15. So x=.15/.25, and x=.6. Again, I could be off but that was my thought process.

I have the same thought process, but i'm also unsure because i couldn't find an explanation of that type of problem.

Here are some standard probability formulas.

This thread has been a life saver for a lot of us and I do not want to belabor the awesome information that a lot of people put up on this thread. So I will only include some observations that I have made while taking the test that I have not seen posted thus far:

OAR portion: You are penalized much harder for incorrect answers than if you don't answer at all. I timed out on all three portions and still got a 57. Remember, this entire test is about accuracy FIRST, then Speed.

Dichotic Listening: The pace is quite slow and makes this portion very easy. Lean to the target ear and HERE IS WHY! You may have a lot of perceived pressure of the test and you may have spurts where you just blank out [especially during the combined PBM portion]. Leaning will remind you what ear you are listening too. Also, repeat EVERYTHING in the target ear. This will help you because if you do not repeat you may second guess what you heard, repeating the target ear gives you a SECOND CHANCE!


PBM: Regarding the multi-tasked portions of this event, focus on the additional tasks. For example, during the 2d/vertical/ dichotic, focus on dichotic FIRST, then find out which will be your second priority (I surprisingly had an easier time tracking 2D peripherally rather than the vertical plane and you will find out quickly which plane you take to better). Remember, being an aviator is about your ability to shift focus quickly and trying to do all of them at once is extremely difficult (however, some of you are flat out gifted!) Prioritize the evolution and shift your focus quickly. Crush it!

Lastly, thank you all to those that have contributed to this thread. Your contributions have been invaluable and afforded me [and many others] the opportunity do well on the test and pay any experience forward.

What? You get penalized for wrong answers too now?? It wasn’t the case before.
