No math in mine. Not sure if you could call it physics, but I had several questions which showed networks of gears and it would tell you which direction gear A is spinning, then ask you which direction gear e was spinning, or "how many gears are spinning counter clockwise in this system?"

I didn't study for mech and don't have any experience with tools. I guess the test is judging your ability to learn how to fix an aircraft, not your ability to fix an aircraft.

It wouldn't hurt to learn about the different car systems though. I was asked a couple specific car questions that I just happened to know about because of something from my past, so there's that.
