the Air Traffic Control Career Prep book is great (make sure you download the update...send me a message if you need the link).....but if anyone wants some extra help with the math section i also got something that explains the way you do ATC math about 100X better than the book, and it has TONS of example questions. if you would like it just send me a message with your email and ill shoot it out to you.(and i promise it will definately help....there was a single math question i didnt know. i answered every math question with 100% confidence that it was right)
also, if you have any questions about the test let me know...i took it just a little over 2 months ago, and i should be able to remember some stuff.
