Libraries
Study Guide Overview
This AP Computer Science Principles study guide covers program design (modularity, code reuse, libraries, APIs), data and information (data types, data structures, data abstraction, data representation), algorithms and programming (control structures, algorithm design, testing, debugging), and the global impact of computing (innovations, digital divide, cybersecurity). It includes practice questions (multiple choice and free response) with scoring rubrics and emphasizes exam strategies.
