I don't know if this is really a thing anymore but I'm going to post about my experiences with it.
I used the Barron's book and just about every study guide/posts I could find on here.
The math was simple to me (but math typically comes easy to me), I took my time and wrote out the problem. I was more concerned with getting the right answer than speed. A lot of the practice problems and what has been discussed previously covers this section well. There seems to be a lot of questions about number of hours it takes a certain number of people or things to complete a task, and the method to these is find how many total man hours are required to complete it, how many hours each person does, and then find the new time with the total number of people or machines.
The reading was a crapshoot to me, I couldn't tell whether I was getting it right or wrong, and I couldn't tell whether the questions got harder or easier. A lot of the practice problems I found had pretty clear answers, but I found these to be more confusing and struggled to pick between it. In Barrons this section had definitions of random words, which I didn't have on the test. None of the passages seemed too in depth, and were simple to read, but the answers weren't very clear.
The mechanical section for me was much easier than I was expecting. It was mostly intuitive, a couple problems where you actually had to calculate it out but for the most part I could just look and figure it out easily. I think I got lucky, because I really only had problems on questions that I was comfortable with, and not ones that I wasn't. Not much on electricity.
My ANIT test was easier than I was expecting, I studied some but felt I would be unprepared. I think this is just you either get lucky studying the right stuff or you don't. Definitely know the parts of a plane and boat and how a plane moves and works (rudder turns l/r, boat/plane moves ___, elevator goes up, plane ___, and the axis and what controls effect that, and I guess just try to read up on your Navy and Military aviation history, you may get lucky or just screwed.
I hated the personality test, it was soo long and I felt I would just randomly choose between options because neither applied to me.
The parking lot test is all practice. Get familiar with it. There are eight possible compass orientations, so I drew them all out on a paper. For the simple you are going N, S etc I could just look at the picture, but for NW etc I needed to look at my paper. This slowed my time down but made me more accurate. I got a few wrong because I was nervous and rushing, but overall I think I did okay. The biggest thing I didn't realize going into this was how important speed was, the other stuff I read suggests getting a time of around 2 seconds, which is just really quick to be able to look at one side, determine what you are looking for, look at the other side and figure it out.
The hearing test wasn't too bad, for some reason I was better on my right than my left but I think it was fairly easy.
The tracking the plane with the throttle was the hardest part for me, no matter what I did I felt like I couldn't get it on the dot. The throttle would go to fast, then too slow and just slide right over the target. The joystick was better, and just using it was good, but combined with other stuff I sometimes had trouble with the up and down direction. It was also really hard to focus on both moving targets, but I found myself focusing on the joystick one, and trying to glance over and constantly move the throttle to get somewhat lucky. Adding the sounds in wasn't actually too much harder, and I think I did okay with this section overall, but it felt like I was doing terrible at the time.
For the emergency procedures I wrote them on my paper, and put which finger I would use to control which knob, and what I need to do. This was easier than memorizing, and I was able to complete them quickly before my screen got red, so I think I did pretty good on this section.
On my throttle, the button you press for the left ear wasn't actually the right one labeled, and I had to press random buttons until I figured out which one actually worked instead of it (which I think is annoying, I asked my recruiter because it seemed like something was wrong and I didn't want to take it and get fucked, but she made it seem like this was normal/happening again, so just be prepared for some of the controls not to work and to troubleshoot it).
I got 68, 8/7/8 and have a GPA of 3.12, with I think some pretty good LORS, volunteer and leadership, so I'm fairly happy but if anyone wants to give an advice on how likely I would get a yes for pilot that would be appreciated
