Full-length practice exam modeled on the official College Board AP Computer Science A exam. 40 Java multiple-choice questions covering primitives, objects, control flow, classes, arrays, ArrayList, 2D arrays, inheritance, and recursion, plus 4 free-response questions: Methods & Control Structures, Class Design, ArrayList, and 2D Array. All Java code follows the AP CSA Reference (Java subset).

Every question is scored instantly with an explanation, and your results feed into your score prediction. For the most realistic read on where you stand, take it in one timed sitting.
AP Computer Science A is a college-level introduction to programming taught entirely in Java. The course centers on object-oriented design: students learn to write, analyze, and debug code using primitive types, objects, methods, control structures, classes, inheritance, and data collections. The current course is organized into four units. Unit 1, Using Objects and Methods, introduces variables, expressions, String methods, and calling existing classes. Unit 2, Selection and Iteration, covers boolean logic, if/else statements, and while and for loops. Unit 3, Class Creation, teaches students to write their own classes with constructors, instance variables, accessor and mutator methods, inheritance, and polymorphism. Unit 4, Data Collections, covers arrays, ArrayLists, 2D arrays, and searching and sorting algorithms. Beyond syntax, the exam rewards algorithmic thinking: tracing code by hand, predicting output, and reasoning about how data moves through nested loops and method calls. Students most often struggle when they memorize syntax without understanding how reference variables, object aliasing, and method return values actually behave. The free-response section demands clean, complete Java written under time pressure, so fluency with ArrayList traversal and 2D array indexing is essential. Effective preparation pairs daily hands-on coding with deliberate practice tracing released free-response questions and reviewing the official Java Quick Reference, which lists the only library methods you are expected to know. Strong students also rehearse common patterns: building and filtering ArrayLists, traversing 2D arrays row by row, and overriding inherited methods. Mastery comes from writing code, not just reading it.
Two equally weighted sections over 3 hours: Section I is 42 multiple-choice questions in 90 minutes (50% of score), and Section II is 4 free-response questions in 90 minutes (50%) covering methods/control structures, class design, ArrayList data analysis, and 2D arrays. Delivered digitally in Bluebook.
Raw points from the multiple-choice and free-response sections are combined and converted to the AP 1-5 scale.
