The AP Computer Science Principles (OLD) exam was a foundational, introductory college-level course designed to introduce students to the essential concepts and practices of the field.<!----> This course was revolutionary for its time, with a mission to broaden participation in computer science and attract students from all backgrounds, regardless of previous programming experience. It was not just for future computer scientists but for all students who wished to understand how computing influences the world. This specific study guide covers the performance tasks and exam format used between 2017 and 2020, offering a powerful way to review the core concepts of that era for practice.
What the Course Entails and Exam Details
The older AP CSP curriculum was built around seven fundamental conceptual areas known as the "Big Ideas," which provided a holistic view of the computing landscape. Students explored creativity as a part of computing, learned how to represent data using abstraction, and analyzed how information is collected, processed, and visualized. The foundational pillars of computer science—algorithms and programming—were central to the course, teaching students to solve complex problems by writing original code. Furthermore, the course delved into the technical structure of the internet and the crucial ethical and societal issues of global impact. This historical framework gave students a comprehensive overview of how digital systems work and their profound effect on modern life.
What to Expect in the Final Exam
The final score for the historical AP CSP exam was determined by two major components, providing a balance between timed, end-of-course questions and long-term project work. The total assessment was split into 60% for the end-of-course multiple-choice exam and 40% for the unique through-course performance tasks.
Section I consisted of 74 multiple-choice questions administered in a single 2-hour sitting, which tested understanding across all seven Big Ideas. These questions included single-select items and an important subset of multi-select questions, where students had to choose two correct answers.
Section II, the through-course performance tasks, were projects completed with a specified number of hours in the classroom during the year and uploaded via a digital portfolio.
The first was the "Explore — Impact of Computing Innovations" task, worth 10% of the total score, which required students to investigate and present on a computing innovation of their choice.
The second, "Create — Applications from Ideas," worth 30% of the total score, challenged students to develop an original computer program and submit its code, a descriptive video of its function, and accompanying written responses.
How to Study and Exam Centers
Preparation for the OLD AP CSP exam requires a dual approach, as mastery of both multiple-choice concepts and the historical performance tasks is required. Your most effective strategy should involve building a practice program that integrates specific components like a list, an original algorithm with mathematical or logical reasoning, and procedures with parameters.
Focus your study on the official College Board archive to find old student performance task responses and the detailed scoring guidelines for the Explore and Create tasks from 2017-2020. This will show you exactly what graders were looking for during that specific era.
For the multiple-choice section, review historical practice booklets and legacy review books to get used to the multi-select and computational thinking questions of that time.
As for exam centers, this test was historically taken in person at authorized AP high schools and was not available through public testing centers like Pearson VUE; students were typically registered through their school's AP coordinator for on-campus administration.
Job Opportunities from the Course
A foundational knowledge of computer science, as validated by this AP exam, unlocks a wide array of career paths, as technical proficiency is now essential in almost every industry. Here is a list of job titles and fields where these skills are directly applicable.
