The AP Computer Science Principles Exam has two parts: the Create performance task—which you’ll complete over the course of the year and submit online for scoring through the AP Digital Portfolio—and the end-of-course multiple-choice exam. Both measure your proficiency in and grasp of the course practices and content, and both contribute to your final AP score on a scale of 1–5.
Starting April 8, you can try out the test-day experience, by answering example questions in the digital testing application. See the Digital Practice page for general information about practice options.
AP Computer Science Principles students will have two options to answer example questions in the digital testing application. Both provide approximately the same time limit per question as the full exam.
We highly recommend you take the Digital Practice, and strongly advise that if you can’t take the Digital Practice, at least take the App Demo. Both can be taken multiple times, and can be accessed directly in the digital testing application. You can access your answers and an MCQ answer key for Digital Practice. Note: Taking the App Demo after completing Digital Practice may override your answers from Digital Practice.
You should be aware of some aspects of testing digitally that you’ll encounter–in the Digital Practice and on exam day:
