Definitely invest in a HOTAS (preferably the same one your recruiting office uses) and get some hours in a flight simulator like MSFS or XPlane so you can get used to the controls and the inverted Y-Axis. Use
Jantzen's tracking sim pretty much every single night until you go back to take the test again, this will help with your peripherals, muscle memory, and speed. Try to remain as calm as possible throughout the other sections of the test so that you're not mentally burned out when you get to the PBM..... that entire section and the ANIT is basically what your PFAR is comprised of so, it's important to really focus and ace it from start to end.
You got this man! Depending on how you did on the ANIT section, I'd mainly focus on scoring higher that PBM. Your OAR & AQR scores show that you're a pretty smart dude so, you should definitely have the rest of the test in the bag when you retake and wont have to worry about losing those other scores... although your PFAR is really the only score out of the four that matters.
Do you have any previous flight experience?
