About These AP Computer Science Principles Practice Tests
These free AP CSP practice tests are designed to mirror the format and difficulty of the actual AP Computer Science Principles exam. Each topic test contains 25 multiple-choice questions aligned with specific Big Ideas from the College Board curriculum framework. Questions use authentic AP CSP pseudocode and include the select-two format found on the real exam.
How to Use These Practice Tests Effectively
Start with the Big Idea that gives you the most trouble. After completing a test, review every explanation, even for questions you answered correctly. Understanding why wrong answers are wrong is just as important as knowing the right answer. Take each test under timed conditions (about 45 minutes for 25 questions) to build exam stamina. Revisit tests after studying to track your improvement.
What Is on the AP CSP Exam?
The AP Computer Science Principles exam consists of 70 multiple-choice questions in 2 hours, plus the Create Performance Task completed during class. The exam covers five Big Ideas: Creative Development (13-18%), Data (17-22%), Algorithms and Programming (30-35%), Computing Systems and Networks (11-15%), and Impact of Computing (21-26%). Big Idea 3 carries the most weight, making the programming fundamentals, conditionals, and procedures tests especially important for your preparation.
