Do I need prior programming experience for this course?

No prior programming experience is required. The course begins with foundational Java syntax before progressing to object-oriented concepts such as classes and inheritance.

Does the exam require writing full programs by hand?

The AP Computer Science A exam includes free-response questions that ask students to write Java code, so this course includes regular practice writing and tracing code, not just reading about concepts.

How is this course different from AP Computer Science Principles?

AP Computer Science A focuses specifically on Java programming and object-oriented design, while AP Computer Science Principles covers a broader introduction to computing concepts. They are offered as separate courses on this site.

AP Exam Preparation

AP Computer Science A

High school students preparing for the AP Computer Science A exam.

AP Computer Science A centers on programming in Java, including how to design, write, and analyze code using object-oriented principles. This course organizes that material into a progression from basic syntax and control structures through classes, inheritance, and common data structures such as arrays and array lists. Because the exam includes both multiple-choice questions and free-response questions that require writing actual code, lessons are paired with opportunities to practice writing and tracing programs rather than only reading about them. Students move through the modules at their own pace and can revisit any topic as needed.

Course modules

Lessons combine explanations of Java syntax and programming concepts with annotated code examples, allowing students to see how a concept like inheritance or iteration applies in working code before practicing it themselves.

Primitive Types and Using Objects

Working with variables, data types, and basic object usage in Java.

Boolean Expressions and Control Flow

Writing conditional statements and understanding program logic.

Iteration

Using loops to repeat actions and process data efficiently.

Writing Classes

Designing classes, constructors, methods, and understanding encapsulation.

Arrays and ArrayLists

Storing and manipulating collections of data using arrays and the ArrayList class.

2D Arrays

Working with two-dimensional arrays and nested iteration.

Inheritance and Polymorphism

Building class hierarchies and understanding how polymorphism affects program behavior.

Recursion

Writing and tracing recursive methods and understanding base cases.

Practice format

Practice sets include both concept-check questions and code-tracing exercises organized by topic, helping students build comfort with reading Java code as well as writing it.

Mock exam format

Full-length mock exams are structured to reflect the general format and pacing of the AP Computer Science A exam, including multiple-choice questions and free-response questions that require writing Java code.

Webinar format

Live webinars led by an AP Computer Science A instructor walk through commonly challenging topics, such as class design and recursion, and include time for students to ask questions about their own code.

Written questions

Students can submit a written question, including a snippet of code they are stuck on, through the platform at any time. Responses arrive through private platform messages, so no student needs to appear on camera to get help.
