Structure of the AP Computer Science Principles Exam 

The AP Computer Science Principles (AP CSP) exam is designed to assess students' understanding of foundational computer science concepts and their ability to apply them creatively and analytically. The exam structure includes two main components: a multiple-choice written exam and a performance task submitted before the exam date. Together, these components evaluate both theoretical knowledge and practical skills. 

1. The Written Exam 

The written portion is taken during the official AP exam period in May and consists of 70 multiple-choice questions divided into two main categories: 

1. Single-Select Multiple-Choice Questions 

• These questions have one correct answer and assess students' understanding of core concepts. 

• Topics include algorithms, programming, the Internet, cybersecurity, data analysis, and computing's societal impacts. 

1. Multi-Select Multiple-Choice Questions 

• Students must select two correct answers from four options. 

• These questions test deeper comprehension and critical thinking. 

Exam Format 

• Duration: 2 hours 

• Scoring Weight: The written exam accounts for 70% of the AP CSP score. 

• Question Break : thinking and algorithms 

• Understanding and using data 

• The role and functionality of the internet 

• Cybersecurity and global impact of technology 

1. The Create Performance Task 

The Create Performance Task is a project that students complete during the school year and submit digitally for scoring. It evaluates a student’s ability to design and implement a computing artifact, such as an app, simulation, or game. 

Key Components 

• Program Code: Students must write a functional program using a programming language such as Python, JavaScript, or Scratch. The program should include at least one algorithm and the use of abstraction (e.g., functions or procedures). 

• Written Responses: Students answer several prompts explaining their code, the purpose of the artifact, and how it addresses a real-world problem or need. 

• Video Demonstration: A short video (1–2 minutes) showcasing the program in action must be submitted. 

Scoring Weight 

The Create Performance Task constitutes 30% of the total AP CSP score. 

Timeline and Submission 

Students typically work on the task over several weeks during the school year. It must be completed and uploaded to the College Board’s digital portal before the AP exam in May. 

1. Skills Tested on the Exam 

The AP CSP exam emphasizes these skills: 

• Computational Thinking: Problem-solving using algorithms, patterns, and abstractions. 

• Data Analysis: Understanding, visualizing, and making decisions based on data. 

• Programming: Writing and explaining functional code. 

• Ethics and Impact: Evaluating the societal and global implications of technology. 

1. Scoring and Results 

• The AP CSP exam is scored on a scale of 1 to 5, with scores determined by the combined performance on the written exam and Create Performance Task. 

• A score of 3 or higher is typically required to earn college credit or placement, though this varies by institution. 

The AP CSP exam’s structure balances theoretical understanding with practical application. Combining a written exam and a creative performance task allows students to demonstrate a broad and deep understanding of computer science principles, making it accessible and engaging for many learners.
