What is the AP Computer Science Principles exam?

The AP Computer Science Principles (AP CSP) exam is a College Board Advanced Placement exam that introduces students to the foundational concepts of computer science and challenges them to explore how computing impacts the world. Unlike AP Computer Science A (which focuses on Java programming), AP CSP takes a broader approach covering algorithms, data analysis, the internet, cybersecurity, programming concepts (in any language), and the societal impacts of computing. Students can earn college credit by scoring 3 or higher.

What topics are covered on the AP CSP exam?

The AP CSP exam is organized around five big ideas: (1) Creative Development — iterative design process, collaboration, documentation; (2) Data — binary representation, data compression, data analysis, visualization; (3) Algorithms and Programming — sequencing, selection, iteration, lists, procedures, debugging, searching/sorting); (4) Computing Systems and Networks — internet protocols, packets, fault tolerance, cybersecurity, encryption); (5) Impact of Computing — legal and ethical concerns, data privacy, bias in algorithms, crowdsourcing, open source. All five areas appear in both the end-of-course exam and the Create Task.

What is the AP CSP Create Performance Task?

The AP CSP Create Performance Task is an independent project where students develop a program in any programming language of their choice (Python, JavaScript, Scratch, App Inventor, etc.) that demonstrates algorithmic thinking. Students must submit written responses explaining their program's purpose, the algorithm they developed, how data is stored and used, and how the program could be improved. The Create Task counts for 30% of the final AP CSP score. The remaining 70% comes from the end-of-course multiple-choice exam.

How many questions are on the AP CSP exam?

The AP CSP end-of-course exam consists of 70 multiple-choice questions — 57 single-select and 13 multi-select questions. The exam is 2 hours long. Questions test all five big ideas and six computational thinking practices. The Create Performance Task is submitted during the school year (April deadline) and scored separately. Combined, the exam (70%) and Create Task (30%) determine the final AP score on a 1-5 scale.

What programming languages can I use for AP CSP?

AP CSP allows students to use any general-purpose programming language for the Create Performance Task. Popular choices include Python (most commonly used), JavaScript, Scratch (visual block-based, acceptable for AP submission), App Inventor (mobile apps), and Java or C++ for students with prior experience. The AP CSP exam itself uses a pseudocode notation (defined in the AP CSP reference sheet) for multiple-choice questions — students must understand this pseudocode regardless of which language they use in their Create Task.

How do I prepare for the AP CSP exam?

To prepare for the AP CSP exam, complete practice with all five big idea areas — especially Algorithms and Programming (which has the most questions) and Computing Systems and Networks. Learn binary representation (converting between binary and decimal/hexadecimal), understand how the internet works (TCP/IP, DNS, HTTP, packets), and study encryption concepts (symmetric vs. asymmetric, Caesar cipher, public key cryptography). Use College Board's official AP CSP practice exam and AP Classroom resources. Work through programming problems in Python or pseudocode to strengthen your algorithm design skills before the May exam.
