The ATP Knowledge Test Prep App is the fastest way to ace your FAA Part 121 Written Exam! Our main goal is to keep you updated with the latest test bank! Questions are added, changed and deleted throughout the year. When they are, we'll update them as soon as possible. For the Part 121 ATP Written, there are well over a thousand questions. Don’t be fooled by other apps that only offer a fraction of the test bank! Note: Many questions refer to figures from the FAA's Computer Testing Supplements. Since they are free to download from the FAA’s official site in PDF format, they are not included to keep the apps' file size as small as possible for your device. If you do want to see the figures for the questions, they can be downloaded at faa.gov/training_testing/testing/supplements/ Features: • Simple to use interface recommended by Flight Instructors. • Scores, the date and time taken for quizzes and tests are saved to keep track of your progress. • Questions and answer choices are random just like the real exam! • Optional sound effects for selected answers in Quiz Mode. • Shocks! Answer incorrectly and feel your iPhone vibrate! (This can be turned on and off.) • No internet connection required. Modes: Quiz Mode - While taking a quiz, correct answers you choose are shown in green while incorrect ones are shown in red. Test Mode - Simulates the test you are going to take at a FAA Knowledge Test Center. In this mode, you are asked 125 questions that are pulled from the entire question bank. Study Mode - Here you can read all the questions with only the associated correct answers!
