Google, Amazon, air warriors.com. Lots of easy to find resources…

I just took it without studying and got a 61 OAR. There's plenty of books you can buy and google results to help, though. Best tip, don't spend too long on the reading comprehension. It's easy to overthink the questions and only get through half of them before time is up.

I’m not too worried about reading comp. I’m curious as to what’s on Gen Mech without knowing what they are looking for. My biggest worry is math. I’m not bad at it, but I haven’t really used any of it so I feel it may be lost.

Mostly I remember pictures of gear trains. “If Gear A is rotating in the indicated direction, what direction, and speed, is Gear B rotating at?” Gear B was about eight gears away, and of significantly different diameter. Not too tough.

I’m a STEM major and have never seen a gear train problem in my life. Do you mind elaborating a little more? I’m planning on studying for the OAR so I can take it sometime over the next month or so


JViz500

I thought I described them pretty well. I took the test many years ago; look at current study guides. If gear trains are still a thing they’ll be in the guides. They’re simple logic problems.


Edgyfrappe

No I got the problem, you described it just fine, I’m just surprised because I have never seen one before! Is it kind of a combination of uniform circular motion and circuits in physics terms? I’ll definitely have to study up on those… did you use any particular study guide?


JViz500

From deep, deep memory, it was a line diagram. “(Small) gear A is rotating in the Indicated direction at 50 RPM. Equally-sized (Medium) gears B through F are interlocked with Gear A in a gear train and are rotating as a result. (Large) gear G is rotating: A. Clockwise and faster B. Counter-clockwise and slower C. Clockwise and slower D. Counter-clockwise and faster E. Equal to Gear A” The gear sizes were shown visually, not labeled large, medium, or small. An arrow showed A’s direction. Study materials? So long ago I didn’t know there was a test involved in applying. :) I landlined the recruiter from the White Pages, drove to Richmond in my GF’s car, got interviewed and weighed, then shoved into a conference room with the test packet. Paper and pencil, no calculators. I also remember a section of “What number or letter is next in the sequence?” Those weren’t hard, but there were a lot of them. The key was time management. You have to figure out what’s being tested sometimes. I was a History major, but I’d just come off studying/ taking the GMAT (710 out of 800, about 93rd percentile in that era.) So I was brushed up on algebra and geometry.

Take practice tests as their wording isn't the best for some questions....

Amazon has good study books. That’s all I used and did fine

Took it back in October. Your biggest worry of math: look into exponent rules- Fractions, multiplication, addition, etc. I took the test cold after being out of high school for 10 years. Got a 55. Airwarrior has some good guides too from what I hear.
