It will be up to you to analyze sources of error and determine any uncertainties in your measurements. You’ll also have to draw accurate inferences from observations and data and be able to communicate results in a scientific manner. This includes suggesting how experiments can be improved and proposing new questions to study. At least 20 percent of the course is in a laboratory, and students are required to have a lab notebook and maintain a portfolio of lab reports.

Succeeding in the course and the AP Physics C Electricity exam requires effective practice. The app’s available Learning Tools leave little to guesswork, focusing on topics that are sure to be covered. Full-Length Practice Tests are perfect for testing your ability to answer complex questions and handle the material in the format of the exam. You can practice with word problems and equations, identifying vectors and scalars, and with the graphs of functions. Vector mathematics is used for solving physics problems at this level and is therefore an area to practice as well. With the app’s exercises, you’ll have many opportunities to perfect your skills. Both the full tests and the shorter concept-specific practice tests allow you to view your score. You can track your performance on each question, including how long it took to answer, and view your percentile that compares how you did to everyone else who took the practice test.

The app also includes flashcards, which you can select based on individual topics. They enable you to quickly view questions, and they provide answers, with immediate feedback and the option to continue with as many as are available. The flashcards are pre-made, or you can customize them with video, audio, and text to personalize your study experience for maximum efficiency. The Learn by Concept interactive syllabus is another feature that focuses on individual topics. It lets you continue your studies with questions and answers (with explanations) on all relevant problems available. Lastly is the Question of the Day, chosen from a rotating list of items on the Full-Length Practice Tests. It offers a quick study session that will further give you exposure to the randomness of the test.

All of these features are at your fingertips with the Varsity Tutors AP Physics C Electricity app for iPad, iPhone, and Android, which can be downloaded from iTunes and the Google Play Store.
