gouge = "inside information"
I believe studying the ANIT syllabus on the app is sufficient enough to
learn, but one should practice extensively using the
CRAM flashcards. Common consensus from recent test breakdowns show a trend of very little history or naval/boat questions. You'll get a ton of questions regarding parts/axes of a plane and their functions, runway/taxiway/glideslop/ATC lights and signals, and possibly some questions about rates/jersey colors.
The good thing about ANIT is it's totally memorization based...so if you PREPARE well you will DO well.
