What Is AP CSA?

AP Computer Science A (AP CSA) is an Advanced Placement course and exam administered by the College Board that teaches introductory Java programming. The curriculum covers object-oriented programming, data structures, algorithms, and standard Java libraries. Students who score 3 or higher on the exam may earn college credit at participating institutions, including over 1,400 U.S. colleges and universities according to the College Board’s 2025-2026 Credit Policy database. The course is equivalent to a first-semester college computer science course, typically CS 101 or Introduction to Programming.

What Topics Does the AP CSA Exam Cover?

The AP CSA exam covers seven major topic areas defined by the College Board’s 2025 Course and Exam Description. These include primitive types, using objects, Boolean expressions and if statements, iteration, writing classes, arrays, and ArrayList. The exam also tests recursion, inheritance, polymorphism, and standard search and sort algorithms. According to the College Board’s 2025 AP CSA Course Description, approximately 30% of the multiple-choice questions focus on object-oriented programming concepts, 25% on data structures, 20% on algorithms, and 25% on basic Java syntax and control structures.

How Is the AP CSA Exam Structured?

The AP CSA exam consists of two sections: multiple-choice questions and free-response questions. The multiple-choice section contains 40 questions to be completed in 90 minutes, worth 50% of the total score. The free-response section contains 4 questions to be completed in 90 minutes, also worth 50% of the total score. According to the College Board’s 2025 AP Exam Schedule, the exam is typically administered in the first two weeks of May. The free-response questions require students to write Java code that demonstrates understanding of inheritance, arrays, ArrayList, and recursion.

AP CSA vs. AP Computer Science Principles: Key Differences

Feature	AP CSA	AP CSP
Programming language	Java	Block-based (MIT App Inventor) or text-based (Python, JavaScript)
Exam format	40 MC + 4 FRQ	70 MC + Create Performance Task
Course focus	Object-oriented programming, algorithms	Computational thinking, internet, data
