One course that can be particularly beneficial for students interested in STEM fields is AP Computer Science A. Keep reading for an overview of the course, details on what you need to know for the exam, and expert tips on how to excel!
AP Computer Science A Overview
AP Computer Science A is a college-level course designed to introduce the fundamentals of computer science. Whether you're interested in pursuing a career in technology or simply want to enhance your problem-solving skills, this course provides a solid foundation in computer science principles and programming.
Units Covered and Prior Knowledge
The course is divided into ten units. Your teacher may choose to organize the course content differently based on local priorities and preferences.
- Unit 1 - Primitive Types: Fundamentals of Java, a programming language, as well as other foundational concepts for coding
- Unit 2 - Using Objects: Reference data as a way to represent real-world objects in a digital world and methods to perform more complex operations
- Unit 3 - Boolean Expressions and if Statements: The building blocks of algorithms and using conditional statements to solve problems and control results
- Unit 4 - Iteration: Iteration, another building block of algorithms that are for repetition
- Unit 5 - Writing Classes: How real-world interactions can be expressed digitally by organizing behaviors and attributes into classes, and the legal and ethical implications of computer programming
- Unit 6 - Array: Techniques and standard algorithms to work with collections of related data, known as data structures
- Unit 7 - ArrayList: A deeper dive into data sets, exploring ArrayList objects for larger amounts of data, as well as the privacy concerns related to personal data storage
- Unit 8 - 2D Array: 2D arrays and experimenting with data sets represented in a table
- Unit 9 - Inheritance: Manipulating programming without altering existing code by using subclasses to create a hierarchy
- Unit 10 - Recursion: Solving larger problems by solving smaller, simpler versions of the same problem using recursive methods
Students are expected to have a basic understanding of algebra and problem-solving skills prior to enrolling in this course.
