From what I remember, for the mechanical portion, it wasn't a lot of math, mostly concepts. I used kyle's study guide and that was plenty for me. It'll be similar to what you'd see in an intro to physics course. As long as you understand the concepts behind gravity, momentum, mass, etc, you shouldn't have any problems on this portion.
The dichotic listening portion was a wild ride. There's letters and numbers coming at you from both ears. It's very difficult to prepare for. All I can stress is that you listen to the directions, only listen to the ear they tell you to listen to, and hit the button when they tell you to. And when it gets combined with the throttle and stick, I prioritized:
- Listening
- The stick
- The throttle
When I did this, I really did kind of zone out how other people have said. You just focus on listening, look at the 2d target, and keep the throttle target in your peripheral vision. Just focus on listening and do your best to track the targets at the same time.
It also really does help if you lean into whatever ear you're supposed to be listening to.
