I just finished my First Attempt on the ASTB and scored a 41 3/3/3...
Math: was very straightforward. Surprisingly, I did not have much probability, such as dice/card problems, but I did end up with lots of algebra and geometry-based questions, which were straightforward with the formula sheets that you are given.
Reading: Can't say much about it. self-explanatory but not bad.
Mechanics: Did not study for it except to know about bernoulli's principle and I only had 2 questions about it. Not much math but lots of circuit and RPM questions. I definitely got a good understanding of Work, Energy, and Power because they asked many easy questions, as simple as choosing the correct formula for Work, for example.
ANIT: Be sure to know the in's and out's of aircraft and the type of aircrafts that are still being flown! Didn't get many questions about Airspaces which I was glad because I was having a hard understanding but do know the VFR's and IFR's heading i.e. IFR 001-179 (5k,7,9k,etc) and VFR 180-360 (2500,4500,6500) and know the runways such as the color on taxiways, runways, location/direction sign etc and know the lights that pilots must when they are on the ground or in flight i.e. "what does it mean when the aircraft is on the ground and sees a flashing white light" "Plane wanting to land sees a solid red light, what does it mean?"
PBM: Terrain bombed it for me so bad, I tried so hard to understand the pencil method, but I was still just not comprehending it for the love of Christ. UAV was also not my strongest but I know it was due to the anxiety I was feeling while taking the exam. I downloaded the ASTB prep app on IOS, and I did great in all of the PBM tests and didn't miss a single question on the hardest UAV difficulty, but I panicked and knew I was messing up big time. The same goes for the cockpit simulator. I did super mediocre when I knew I could lock on really well for a long period of time. The only portion I aced with flying colors was the Dichotic Listening, the first attempt by itself, and the 2nd attempt while also doing the cockpit simulation target.
Overall: Although I felt prepared, I let my anxiety and nervousness get the better of me, and I know I will be studying more rigorously. if you haven't downloaded the ASTB prep app I highly recommend it because the OAR portion really helped me out a lot and so did the PBM's
If you guys have any more ideas on how to help a fellow peer out, I am all ears and if someone can REALLY help me out with the Terrain portion that would be awesome
