Understanding the Course
AP Computer Science A is a more advanced college-level introductory course that's ideal for students who want to pursue careers in software engineering, web development, and design.
The course is designed for students who are already familiar with the basic approach of computer science and have a keen desire to learn more. High school students need to have their linear algebra course before opting for the AP computer science A exam.
The course focuses on the programming language Java, which students can practice hands-on while developing programs.
Here are the 10 basic learning units that make up the AP Computer Science A course framework:
- Unit 1: Big Idea 1 - Creative Development
- Unit 2: Big Idea 2 - Algorithms and Programming
- Unit 3: Big Idea 3 - Internet and Networking
- Unit 4: Big Idea 4 - Data and Information
- Unit 5: Big Idea 5 - Global Impact
- Unit 6: Big Idea 6 - Computing Systems
- Unit 7: Big Idea 7 - Data and Information
- Unit 8: Big Idea 8 - Algorithms and Programming
- Unit 9: Big Idea 9 - Internet and Networking
- Unit 10: Big Idea 10 - Computing Systems
Comparing the Courses
The two AP Computer Science courses, AP Computer Science A (APCSA) and AP Computer Science Principles (APCSP), have distinct approaches to teaching computer science.
APCSA focuses on the Java programming language, whereas APCSP is language-specific.
APCSA requires prior knowledge of Java, while APCSP is designed for students with no prior knowledge of computer science.
APCSA is a more advanced course, best suited for students who enjoy coding and programming.
APCSP, on the other hand, is a non-specific programming language course, making it a good option for students who don't have a strong background in computer science.
Here's a comparison of the two courses:
Both courses have their advantages, but it's essential to note that earning college credit by passing either exam is challenging.
What Makes Up a Course?
The AP Computer Science A course is a more advanced college-level introductory first-year computer science course that covers a range of topics, including programming languages, data structures, and algorithms.
The course is organized into 10 commonly taught units of study, which provide one possible sequence for the course. You have the flexibility to organize the course content as you prefer, whether you're a teacher or a student.
The course framework provides a description of the course requirements necessary for student success, with a focus on big ideas that encompass core principles, theories, and processes of the discipline. This framework encourages instruction that prepares students for advanced computer science coursework and its integration into various STEM-related fields.
The course covers a range of topics, including primitive types, objects and methods, wrapper classes, and iteration. It also covers class structure and keywords, arrays, ArrayLists, and 2D arrays, as well as inheritance and recursion.
Here's a breakdown of the topics covered in the course:
- Primitive types — manipulating variables and data types.
- Using objects and methods.
- Using wrapper classes and the math class.
- Boolean expressions and if statements.
- Iteration: while, for loops, as well as nested iteration.
- Class structure and keywords.
- Arrays, ArrayLists, and 2D arrays.
- Inheritance (subclasses and superclasses)
- Recursion — introduction to entropy, absolute entropy, and entropy change.
The course uses Java programming language and covers a range of topics that are essential for software engineering, web development, and design.
Exam Format and Structure
The AP Computer Science A exam consists of two portions, with each section making up 50% of the final scoring weightage. Section I is a multiple-choice section with 40 questions, each worth 1 point.
Students are required to fill in the bubbles with a pencil on the mark sense sheet for the correct answer. The questions in this section are machine-scored and cover topics such as code errors, predicting output, and determining input.
Section II is a free-response section with 4 questions, each worth 9 points. These questions assess knowledge of Java Syntax, including control structures, methods, classes, one- and two-dimensional arrays.
The free-response questions in Section II are scored by AP human readers and can involve writing or designing an entire class. Students should handle this portion with great care, as each question is carefully examined by multiple graders to ensure authenticity and reliability.

Step-by-Step Study Guide
To prepare for the AP Computer Science A Exam, it's essential to understand the exam format. The exam consists of two portions, each holding a 50% weightage in the final scoring calculation. The exam is divided into two sections: multiple-choice and free-response.
The multiple-choice section includes individual questions, typically 2-3 questions per set. Computational Thinking Practices 1, 2, 4, and 5 are assessed in this section, while Computational Thinking Practice 3 is not.

To prepare for the multiple-choice section, practice identifying the proper parameters to use when calling methods of classes that are provided to you. Pay close attention to the method descriptions and use the correct type and order of parameters when calling methods.
Here are some reliable free resources to help you practice multiple-choice questions:
- Albert.io
- Smore’s list of APCS resources and practice tests
- Varsity Tutors
In addition to practicing multiple-choice questions, it's crucial to practice free-response questions. The free-response section includes four questions that assess Computational Thinking Practice 3: Code Implementation. Each question focuses on a specific skill, such as methods and control structures, classes, arrays/ArrayList, and 2D arrays.
To prepare for the free-response section, practice writing short programs and calling methods of classes that you have not seen before. Pay close attention to the method descriptions and use the correct type and order of parameters when calling methods.
Here are some reliable free resources to help you practice free-response questions:
- Albert.io
- AP College Board APCSA Past Exam Questions
- CodeHS practice problems
- Smore’s list of APCS resources and practice tests
Remember, practice is key to success on the AP Computer Science A Exam. By practicing multiple-choice and free-response questions, you'll be well-prepared to tackle the exam and achieve a high score.
