AP Computer Science A

Master object-oriented programming in Java and prepare for top marks on the College Board AP Computer Science A exam.

This course delivers an exhaustive exploration of object-oriented design and algorithm development using the Java programming language in direct alignment with the College Board curriculum. Students learn foundational concepts spanning primitive data types, control structures, custom class design, dynamic data structures, and algorithmic efficiency. Through targeted programmatic problem-solving and rigorous exam-style tasks, learners build the computational thinking required for high performance on both the multiple-choice and free-response sections of the AP exam. Every lesson includes tutor notes, a video, a hands-on lab, exercises and a 12-question quiz you must pass at 80%, followed by a pooled final exam and free and paid practice tests. Erudex is independent and not affiliated with College Board.

You will learn to

Design, implement, and analyze modular, object-oriented solutions to computational problems using core Java syntax.
Formulate complex decision and repetition algorithms using compound conditional logic, nested loops, and recursive functions.
Manipulate standard static and dynamic linear collections, including 1D arrays, 2D arrays, and ArrayList objects.
Apply the principles of abstraction, encapsulation, and inheritance to architect reusable class hierarchies and evaluate polymorphism.
Evaluate code efficiency and correctness by tracing execution, analyzing edge cases, and anticipating runtime behaviors.
