Sporty's Study Buddy will prepare you for the FAA written test like no other study tool available with three modes of operation. Test material is expertly organized into categories based on subject matter and includes, questions, answers, correct answers, and detailed explanations. • STUDY QUESTIONS BY TOPIC • Learning Mode allows you to create custom review sessions by selecting exactly which categories you want to review. Each session randomly generates the question order, and provides instant feedback based on your answer selection. Each question also provides a detailed description as to why each answer is right or wrong. These explanations were developed by Sporty’s team of Master CFI’s, based on their experience preparing students for the Private Pilot certificate • REVIEW QUESTION FLASHCARDS • Flashcard mode tests your knowledge by allowing you to only see the question without the answer choices. After answering the question mentally, you can then select to show the correct answer, and self-grade your progress along the way. This is a great feature that keeps you from being distracted by incorrect answers! • TAKE PRACTICE TESTS • Test mode randomly generates a 60-question session from the entire database of published FAA test questions, simulating the real Private Pilot test. After answering all the questions, you’ll be given instant results, and have the option to review either all the questions, or just missed questions. Included in the review session are the same detailed explanations for why each answer is right or wrong. •PROGRESS REPORTS• After completing each test your results are saved in the app's Progress Report section, where you can review previous scores and and a detailed history of each question and answer selection. You can also pause a partially-completed session, and resume it at a later time here.
