The Computer Science A Exam will test your understanding of the programming concepts covered in the course units, as well as your ability to read and write code for computer programs.
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 A 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 solution materials (MCQ answer key, FRQ scoring guidelines) for the 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 they’ll encounter–in the Digital Practice and on exam day:
