CommStudy is THE app for studying for the written portion of your FCC Commercial License exam! Download this FREE app and try out the sample Elements! Each sample contains only 20% of the questions contained in the full Element. If you decide you want to purchase the full Element, this is done via an in-app purchase. All seven elements are included: 1, 3, 6, 7, 7R, 8, and 9. FCC Commercial License exams are composed of questions from a pool. Use this application prior to taking your exam to review and practice all possible questions. Then, test your knowledge with practice exams! Some questions require you to review associated Figures. On the iPad, the figures appear below the question. These figures may be zoomed and panned on the iPhone/iPod touch. After completing your first practice exam, the question pool screen will display your proficiency in each question subelement/topic for all practice exams you have completed. This will help you determine what areas need further study! You may choose to receive immediate feedback on right and wrong answers when taking a practice test or you can wait until the test is completed and review the questions in the Test History section. On practice tests, no question will be repeated until all of the questions have been used in a particular subelement/topic. The practice tests do adhere to the requirements of the actual tests. They are each composed of the proper number of questions from each section of the corresponding question pool. An in-progress practice test can be resumed if you exit the test or the application. This app has these additional features: • Portrait and Landscape support on iPad • Swipe gestures to navigate between questions • Tap on answer to select it • Buttons to skip to next/previous wrong answer in test history • Configurable Test Settings • Optional randomizing of test answers • Optional auto-advance during test
