AP Computer Science A

Java fundamentals, object-oriented design, and data structures—with FRQ practice and code tracing that match the format and rigor of the exam.

Exam overview

What's on the exam

AP Computer Science A is taught in Java and focuses on programming methodology, data structures, and object-oriented design. The exam includes multiple-choice questions on code reading and tracing, plus free-response questions that ask you to write methods and sometimes full classes—exactly what we practice.

Key topics we cover

Units & skills

Primitive types, objects, and the Math and String classes
Boolean expressions, conditionals, and iteration
Writing classes (constructors, methods, encapsulation)
Arrays and ArrayList
2D arrays and algorithms (search, sort)
Inheritance and polymorphism
Recursion
FRQ strategies: method design, class design, and array/ArrayList manipulation

How APScholar helps

Built for CSA

We focus on the skills that matter most: tracing code by hand, designing methods that match the problem specification, and avoiding common Java pitfalls (off-by-one errors, null references, inheritance misuse). Our AI gives feedback on your FRQ logic and style, and our question bank mirrors the types of problems the College Board uses every year.
