About the Assessment
The AP Computer Science Principles assessment has two parts: two performance tasks—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 AP Exam. All measure your proficiency in and grasp of the course practices and content, and all contribute to your final AP score on a scale of 1–5.
